I bought this little sampler/sequencer because I thought it was cute, and because I'm a big fan of my PO33 and PO133, which give me a little musical breathing space in the middle of my busy days, without having to turn on the studio. I've also been a "bit" of a sampler/sequencer collector since 1998...

So what is KO2?

For me, it's clearly a minature/modernized clone of the MPC2000XL, with a few improvements and a few things missing (like visual sample editing). It's also very close to a Volca Sample, but on steroids then.

In terms of architecture, the reference to the MPC2000XL is obvious:
- 4 groups of samples (the MPC offers 4 banks of programs).
- step edit mode with +/- key navigation
- quick assignment of samples to pads
- 1 slider assignable per group on a parameter: volume, fx, filter etc., but only one parameter per group. Slider movements are recorded in sequences.
- very basic sample editing (2-parameter envelope, pitch, no individual filter setting on the sample, e.g.) - the MPC2000xl is better in this respect, with plenty of individual sample editing parameters and 4 FX busses if FX card installed)
- each sample can be sequenced on its own track, and sequence length is (finally) extended to 99 bars. But sequence length applies to a group. (in MPC parlance, a 'group' is the equivalent of a PROGRAM)
- swing and quantize (but the MPC has many more timing/quantize options).

The KO2 also has a few gadgets, such as punch in fx, which are totally useless in my opinion (and what's more, you can't record them in sequences), but opinions will differ on this. We don't really care, because you can record slider movements in sequences, so you can record a filter or volume movement on a sequence, or increase the FX, and so on.
The (apparently fragile) slider is very useful: you can control almost all the parameters (filters, FX, volume etc.) one by one, but by sample group, not by pad/sample (with the MPC2000xl you can choose). But it is fragile.

Like the MPC2000xl, the KO2 sounds very good, and there's a nice dynamic range on the audio output. I think the MPC has more 'oomph', but that's subjective.

So what are the limits?
- The thing looks fragile, it's plastic all over, and the keys don't inspire confidence (but compared to the OPZ, they're top quality).
- STEP recording: On an MPC 2000xl, you go into step edit mode, press REC, and there you can enter notes by step, with a very nice function: auto step, which moves on to the next step as soon as the note is entered (depending on the Quantize value). But with the KO, for each step you have to 1) select the step, press REC and the pad, release, then move on to the next step manually. It's totally anti-ergonomic. If I enter a drum break over 16 steps, I'll have to press the KO 3 times more than on my old MPC.
- The rotary encoders, as with the PO33 and 133, are horrible: first they should be infinite, then they should be precise. If you've ever used the PO33, you'll know what I mean. Frankly, it's a bit painful to edit parameters with these. As you do almost every parameter setting with these rotary encoders... they get on your nerves all the time. In short, this is THE BAD POINT of the KOII in my opinion.
- Memory: 64Mb of storage memory in 2023 is really a joke. I insist, it's a bad joke. At the price of memory in 2023, it almost seems like an insult, but that's apparently how it is at TE. With the OPZ and OP1, we also have ridiculous quantities of storage memory, and, let's face it, totally insufficient to use the sampler without a hitch.
- Memory management and connection with the PC is via an online tool, the SAMPLE TOOL (like the Volca Sample, the TE version looks like a basic copy of the Volca Sample 2 management systems), which is very disappointing. Tip: stay on the sample tool page during sample transfer, otherwise the transfer stops and displays FAIL. The ergonomics of this online tool are more than questionable: you will soon be confronted with the limit of on-board memory, and you'll have to 'make room' by deleting unused samples to load/sample other sounds... then the online 'Sample Tool' is worse than useless. Reading the guide, you'd imagine that the samples in use are identified with an orange marker. In reality, these are the samples in use "in the current group and project selected on the KO". So it's a real pain to delete the 'unused' samples. You have to listen to them one by one, and make sure you don't make a mistake. It's hard to imagine a more annoying and inefficient system. And since you can't export (save to PC) a project with its samples and sequences... I'll leave you to imagine. Without an OS upgrade that will allow to make a backup of at least the whole device in a few clicks (after all, 64mb isn't a lot of storage space today on a HD), and even better, per project, this product remains a toy (limited to 9 projects and 64Mb of total sample memory) - while 64MB RAM is OK for a 'cheap sampler', 64MB for sample storage, and no simple system to backup to a PC, is an insult to the modern age.
- Polyphony: TE advertises 12 voices, but I've had a lot of drops even with simple sequences and mono samples, so I'm skeptical. Beware of stereo samples.
- Effects: what can I say, you can choose one effect bus, and only one for the 4 groups. In my opinion, this is completely ill-conceived and very limited. Note that the filter is an effect here, so it's filter or distortion or reverb... but not all three.
- No pattern chain, and here I don't understand, we have that on the OPZ, on the PO33, and not on the KOII? I hope it'll be in a firmware update. But until then, we'll have to wait and see. That's another VERY BAD POINT of the KOII.
- No undo
- No sample reverse function, and of course no LOOP options
- The timestretch mode is fairly intuitive to use (provided you know the BPM of the sample, or you only use 1/2/4 bar samples), but then the result is horrible on melodic loops, and passable on drum breaks. On a piano loop, the algorithm generates a very unpleasant high-pitched whistle. The weirdest thing is that the algo seems to work even when the loop is played at its original tempo. So I put this function in the 'gadget' category with punch in effects.
- the CHOP function: even if the system is not very precise, it's nice to chop up a sample (in non-destructive mode) and have each segment on its pad (but be aware that by default the EP133 will put all the pads in the group in the same MUTE GROUP). The CHOP works... some of the times. Most of the times it don't, and there is no way out... You can't make a basic equal subdivision chop (like the OP33 will do e.g.). Hopefully and OS update will correct this. Eventually the chop menus are practically unusable and the automatic chop... it's useless.
- sample editing: well, it's an abomination (like on the OP1, or on the PO33), you get the machine-gun retrigger when you turn the knob (who needs that?, especially if it plays the start point when you edit the end point). Impossible to concentrate on the sound. Infinite waste of time. Tip: To make the rotary encoders a little more usable for parameter editing, you can press SHIFT when you're using them, and they're a little more precise.
- No 'pad clear' function: once you've assigned a sample to a pad, it seems almost impossible to remove it so that the pad becomes silent again (to use the track as midi, for example). Deleting the pad actually deletes the sample from memory.
- I haven't found any way to save sequences/projects to the PC, you can import/export samples, but not sequences/patterns? Wtf? (you can do that with the Volca Sample 2)
- No p-Locks on the sequencer - big let down here: you could edit each step on any sequence in the PO33 (for pitch, filter and amplitude, and not on the KOII. Add the dodgy STEP EDIT mode...
- The online manual... painful navigation. Give me a simple pdf instead.

What's good? (spoiler alert: not much)
- The limited space and price are very attractive.
- The looks (it's subjective)
- Battery operation is good, too.
- Fun: it's fun to use, it's very immediate, and it sounds good (beware of compressor settings though, they can destroy your mix)
- The live sequencer is very pleasant to use, you can engage disengage REC whenever you want (but not so good for step recording and editing).
- Sequence length: from 1 to 99 bars, as desired.
- The sound, the little compressor
- MIDI, very good implementation, the thing records and spits out everything you send it in MIDI, very immediate.
- 9 projects can be stored, better than the OP1 (OG), but not as good as the OPZ (16 projects). But you can't export projects to PC AFAIK.
- Non-stop sound: A real plus of the KO is that you can do everything without ever stopping the running sequence, including sampling or editing a sample, auditioning other samples, replacing a sample in a pad etc. etc. It's a seamless workflow that's much appreciated (except that your memory quickly fills up... and then you have to stop...).

Conclusion

For a low/mid-range sampler sequencer (between the 100-150€ of a Volca or PO33 and the 600-800€ of an MPCOne, a Polyend Tracker or a Digitakt), the KOII does an OK job. Beginners will find everything they need, and will be able to make rapid progress. Certain design errors (rotary encoders , sample editing, no pattern chain, insufficient storage, no undo, no external save, ...) will destroy the long term value of this.
The sample editing and chopping are so horribly done, as to render the sampler (i.e. and instrument that lets you record samples from an audio source) almost useless. (eventually it is best as a 'sample player' like the Volca Sample) You will end up preparing your samples on the PC.
I think that any MPC1000 on the 2nd hand market does a better job than this thing, for about the same price, even without the JJOS, with a lot of additional functions to boot (and less portability).
I wish all the usual youtube influencers had had a closer look at this before posting their rip-off videos.

Quick edit here. There is an undo mode, whenever the umbrella icon shows on screen you can undo the lastaction by pressing shift+B ( the group key). That’s reallyuseful. I think it is only one level of undo.

On reddit, I see lots of QC issues, the most standouts were the dude with the input and output labeled in reverse, another with two identical pads of the number 2 and another person with his slider completely broken off from the circuit board. I think they hired kindergardens to assemble these things. One guy from Australia thought it would be best to order directly from TE, his arrived broken on arrival. :smh:

Sure, the pad layout comes from the MPCs. But I don't see much influence from the MPC2000xl.

Rather, the Yamaha SU700 sampler seems to be the real influence. We see it in the screen, with the font and colours. Also, the ability to set each track with a different bar length. And the use and naming of scenes and how they function is straight from the SU700.

I was given a KOII for Christmas. (At first I was like -- oh no! I already have five samplers -- and many of them are considered some of the best samplers ever made, so I felt no need for another sampler).
But the KOII is a great machine. The sound is very good and the workflow is really nice. I highly recommend it.

Yhea it's got allot of the SU700 vibes..such a shame Yamaha didn't continue this line it could have easily surpassed all other sampling/seq platforms as it was so ahead of its time.. Ableton in a groovebox in 98 :smoker: had one briefly when it came out, it was so ridden in bugs on the first OS releases, freezes every session that I returned it and ended on a 2k XL ... I was young knew not what I had and no patience for the SU loading time... Wish they'd do a release of this line

Anyway what samplers are you comparing it to and would you mind going into some detail on sound characteristics :popcorn:

This was one of the more insightful reviews Ive read, I threw a bit of salt on it at first reading, as you state that the performance FX are useless, to me they are a highlight/ the remix and live opportunities or vast IMO ..

I can definitely see that this is no MPC when it comes to sampling/sequencing MPC power, but the imidiacy /work speed, portability and fun factor along with speaker and microphone really push me towards it as great backpack sampler ..


Now every time I go and take a listen online I feel I hear that the KO has a better sonics, its got more dimension and a round low end , The MPC1 still seams like the smartest choice/but its just not as live oriented and I feel the sound is a bit more streamlined, its also heavy vs the KO and requires external power.

In my scenario its between:
KO2 + torso t1 +a aira S1
/or polyend play +
/or MPC1
/or Machine+

Including a laptop and 303) ..

So Can you be so kind to share more insight on the sound, I feel I can clearly hear definition in sound of the KO2 vs other morden samplers that's including Elektrons, Akais and Rolands. I also find the FX to be quiet distinct special sounding /viby .. And Im 100% Im not pulling a placebo

hmmm may i ask you why you are not considering the sp404mk2 in that list? i think sonically is pretty awesome, its sampling, chopping and sequencing features are very advanced compared to the ko2, of course it can do less than an mpc but... i really fell in love with this little thingy. it took some time but it has grown on me on a daily basis and now is the first piece of gear i turn on when i have some inspiration. damn, it has better time signature management than my live mk1 :) (of course my mpc1000 with jj beats the sh1t out of it sequencer wise, but they are totally different animals)

Hi Hyena! Thanks for the interest, I admit sleeping on the 404, when it first came out there was something that didnt gel with me iirc but it had a number of updates and is one of the best-selling samplers right now.

Perhaps you can share insight on it, how's the workflow and sample managing /sharing (does it show as HD via USB?) also does it have poly?, read something about it having varpharse algos now, can that be poly chained? Can you adjust /timestreatch samples per step? Does it have complete parameter locks (as in can everything be parameter locked including sample loop trim points? How long can a pattern be (its 16 tracks with independent trackl length? ..

Dunno I could go on but tbh I was considering a MC707 strongly do to its sampling/synthesis along with modular like playback and sequencing, quite a unlimited system but the same can be said for the MPC or NI..

In all honesty I believe my best bets are on the poly ends or prehaps a Teen Engineering,, the OPZ being ideal but the limited sampling/re sampling chopping is defeating flow and a problem is that the synths are quite limited and sound dated /toyish and the full on production quality one can get with NI akai PE is just a miss.

I would love to do pro productions on the go and have live playability.. Traveling Europe right now via backpack, if I was in a stdio environment my choices would differ. But truthfully as of now the Play + or Tracker + give me great flexibility, production value, work flow and live play ability in the most compact friendly package.

The Torso T1 plus multiple small devices is a 2nd pondering (its a great live seq) I'd need to record the performance into a laptop midi arranger though.. Right now a tracker + (both sampling local radio and vinyl shops as I travel, even the mini might be a solution) or just try a controller with laptop or simply learn Renoise that basically turns your laptop into an instrument / I tryed that before and hated the hex and using it with a apple touch strip was far far off from the fluid flow of an MPC.

Dunno..IMO there is still no suitable 100% perfect solution, and we are in '24 :cry:

and apologize to the Thread starter for the thread hijack .. hey its still all sampler talk ;)

The SP404 mk2 app lets you drag and drop samples to slots, but it doesn't show up as a drive on your computer. There's also a bulk import from SD card, but that requires getting samples onto your SD card from your computer first

glide wrote:also does it have poly?

Yes, in chromatic mode you can switch between mono, legato, and poly. Otherwise though notes aren't poly, so you cannot double stack the same kick drum on top of each other.

glide wrote:read something about it having varpharse algos now, can that be poly chained?

You can assign the variphrase algorithms, and in chromatic play poly, and with the right settings a delay will be stretched so that all the polyphonic delays play together as a chord...

not quite sure what you mean by poly chained though... so not sure if that information helps you.

glide wrote:Can you adjust /timestreatch samples per step?

You can adjust pitch per step, but not the varispeed/timestretch algorithm.

glide wrote:Does it have complete parameter locks (as in can everything be parameter locked including sample loop trim points?

No, you can adjust timing in a step, pitch, and volume in microscope... which is as close as you can get to P-locks... but no, you cannot change start/loop/end points... or automate things like gate/loop/reverse etc...

glide wrote:How long can a pattern be (its 16 tracks with independent trackl length? ..

64 bars is the max for a pattern
The SP404 mk2 doesn't really have tracks... it has 32 note polyphony. 16 stereo poly if you've got all stereo samples, but yeah... you can load up mono samples and get more polyphony effectively if you want... but the pattern can use all 160 samples in a projects, just obviously not at the same time.

I'd avoid OPZ at this point... they seem to be out of manufacturing, and there are enough knob popping, double trigger, and warped case issues, that you don't *quite* know what you're going to get. The step sequencer on it is quite amazing for the size though... so maybe worth a try. Frankly though, you'll want an external synth/sampler... what it has on offer is barely useful for sampling given the storage capacity limits.

I'd advise checking out the DirtyWave M8. The model:02 just released, and it's got an LSDJ style tracker, but has some great synths, sampling options, and is overall a solid tracker. With the 02 release (which has a slightly bigger screen, USB-C, and microphone), you are starting to see model 01 prices coming down a bit.

✨ Awesome reply NearTao..

Very insightful and useful info, being able to play variphrase polyphonicly is spectacular.. well done Roland

As for the mate, its a good call but its a bit too game boyish "for me personally"concerning data input.

Might as well get a handheld gammer pc + Lenovo A3 (virtual 3screen display) :hdmi: and run Renoise .. pretty amazing actually to have virtual glasses technology for music making

https://www.youtube.com/watch?v=EeksDjD ... j7uJ3gX4br


Anyhow The PE Tracker is 1:1 button dedicated UI for the most part also being able to play notes/chords and drum in beats via pads is another highlights.. but I will give the m8 mk2 another look (+ midi controllers) heard an album done entirely on it and it sounded dope..

Cheers✌️

sorry for not replying, i wasnt checking the forums, nearTao got you covered :)
if you are considering a laptop, may i suggest instead an ipad for extreme portability? i never gave two pennies to the whole ios stuff , but lately i've been investigating it and wow, i fell into the rabbit hole. i started buying an old ipad air 1st gen for peanuts (80 euros) just to check the koala sampler\sp404 integration, i was amazed by how many good plugins are still able to run on that old piece of gear. i invested some money in apps , in particular AUM and mirack(vcv rack port, full blown modular synth) , and installed a lot of crazy good freebies. now i got a refurbished ipad pro 11" with an m1 chip, so cpu will never be an issue, but if you stick with not too many tracks in a project its crazy what you can do with a very old and cheap ipad. you just have to check which is the maximum ios update you can run on any of the old machines, and check that the apps you're interested in are still compatible. the sp\ipad combo is crazy, i'm not using the koala controller that much, i prefer having aum managing stuff on the ipad, with the sp as soundcard\sampler\midi hub etc... a perfect match.

re: sp i want to add that the latest update brought us microscope editing for patterns among other things, its a great way to edit patterns quickly and in depth. especially if one uses a lot of substeps, you can then edit the velocity and pitch of each of the substeps individually.
