hey guys,

i've been a ghostly observer for about a year now. reading a lot of posts but not chiming in. in part because it has only been in the last 8 weeks that i have been really getting down with this thing. I love it. i have so much to learn but i think i am over the learning curve hump and it's fun as #@!$.

Before i even bought an mpc though i came on this board to figure out what was great and what wasn't. at the time there were a lot of discussions about how the mpc can't do the 303/404 style of loop triggering where you just hit a pad and start the sample associated with that pad going. the answer that i always saw was that the software just wasn't made to be that way and nothing anyone can do could change that.

Just now while messing around i found a "glitch" which does exactly what i want it to do. (i'm using jjos 4.93). basically it is a loop lock technique using "Track mute"

1. go to main screen.
2. hold down any loop activated sample (or more than one) to get my loop (or loops) going.
3. hit "track mute" while still holding down the pad.
4. let go of pad.

voila. i'm still jamming. i'm just not touching anything anymore.

this can be done regardless of whether you have sequence going or not. and as long as you stay in "track mute" you can't stop it. to stop you go back to "main" or any other screen and hit the same pad. but if you want to keep going and even add other layers, you just repeat the same pattern with a different pad or set of pads.



So here is my question(s):

1. is this something everyone knows and i just haven't been ghost riding the forum well enough? (or i missed that update in the jj cycle) if i did miss this at some point, i apologize in advance for wasting other peoples time.

2. if this is a glitch, why can't something similar but a little bit more programmable be.... um.... programmed? it would be great to be able to set a pad to be able to 1. loop and 2. loop indefinitely. on/off switch style.

curious what anyone might have to say about this.

thanks,
josh

wow, what a glitch!!!! Very nice find graasmin.

Yep, i'll have this programmed into the new OS if you all don't mind, except i'll just skip hitting the track mute button and be able to set certain pads to toggle on and off in GPE. That would be sweet for live performance.

Id like the Qlink to have Note On>Duration. The maximum value would be a continual "hold", this way you could trigger continual loops but you could use both hands on the pads. At smaller values Note on duration would be useful for loads of other things too, e.g adding a a hold stage to the amp envelope, in OS1 this would make it AHD and in OS2 AHDSR.

Also you could have the read out like the LFO readout : in beats and ticks e.g 3.48 would hold the sound for for 3 1/2 beats. With the eventual maximum being a continual hold.

i'm copy & pasting this response i gave in another thread. for the record i would also like this added as a feature in os2. some sort of "loop lock" feature.

you can also have samples loop indefinitely by using the 'numeric button' trick in the JJ os.

1. load up your samples.

2. go into TRIM & turn LOOP ON for each sample.

3. go into PROGRAM & set play mode to NOTE ON.

4. if you only want to play one loop at a time, set PLAY mode to MONO. if you want to play a bunch of loops on top of each other, set PLAY mode to POLY.

5. go to any screen (such as MAIN) and put the cursor on any field where you can enter a numeric value (such as the TEMPO field).

6. press and hold the pad you want to loop.

7. while you are holding down the pad, press the NUMERIC button on the MPC.

8. let go of the pad & it will keep looping.

9. hit the NUMERIC button again to deactivate it (so you don't accidently enter numeric values by pressing other pads) .

the loop will keep playing until you hit that same pad again to turn it off. you can go to different screens & change values, etc. & the sample will keep playing. you can even have all 16 pads looping at the same time using this technique. just hit the pad again with the NUMERIC function off to stop the pad from looping.

yeah the numeric button thing is handy.

I checked the LFO rate and it goes up to a value of 99( i.e. 99 beats)
I think the note on> duration idea with this type of time frame would be cool, you could specify how many beats you want your sample loop to play for, and a value of 100 could equal the loop would go until you tell it to stop.

yes.

AHDSR.


YES.

if we had this, i'd set every chopped sample to NOTE ON and then just specify the duration via hold in AHDSR rather than fking with duration in the sequencer. i get goosebumps just thinking about it.

shoot, i'd be happy if "hold" was just an extra parameter stuck into the ADSR screen. it doesn't even have to be incorporated into the image: just give me a H: ____ parameter where you fill in the number of ticks you want the sample to play after you strike it-- one tick -> some large number of ticks.

this wouldn't be like the 404 where 1 tap turns it on forever and another tap turns it off, but it'd be better.

but see... why can't it be that way. it clearly has the capability to do just that. i'm not a programmer, but there must be a way of tricking it into believing the same "glitch" happened without actually hitting "track mute" or "numeric" or whatever.

when a pad is pressed, a note on message is sent. when a pad is unpressed, a note off message is sent. what you do w/ the glitch is bypass the note off, so the note becomes "stuck"

what you're looking to do is 1 tap on, 1 tap off. that's surely doable, it'd be a new specification like

1 - ONESHOT
2 - NOTE ON
3 - 2 TOUCH (first ON, 2nd OFF)

however, much more could be done with AHDSR.

I would love this anyway!

Couldn´t it be both "2touch" and "AHDSR"

By blippo Mon Dec 03, 2007 8:37 pm
o by the way
graasmin

Could you be more specific about this glitch? It seems i can´t get it working, not the numeric either.. :cry:

By blippo Mon Dec 03, 2007 8:41 pm
oh never mind i got it:)

Yep, the various methods for triggering the "loop & hang" glitch have been known in the forum for about a year or so. Last came up in September I think but that thread has disappeared or gotten buried in my post archive somewhere. I had an easier time finding the original posts. Credit goes to Flammable:

Of course it should be a "real" feature by now, probably always should have been...

just give me a H: ____ parameter where you fill in the number of ticks you want the sample to play after you strike it-- one tick -> some large number of ticks.

Yeah this'd be a good way of doing it, cause you could set each pad differently. Q link control would be very cool too of course but this way has the edge. I think it'd be more managable display wise if it was done in beats and ticks, rather than just ticks. Also if you bump it up to the maximum value it'd could become "2 touch" mode, for example after 99 beats 95 ticks= 2TCH or LPLOCK or something.

Also have you noticed that oneshot samples loop in OS2 ?

yes, i have noticed that. since i haven't created a song yet in os2 i haven't figured out whether i like it or dislike it. i really wish this didn't come at the end of the hardest semester i've ever experienced
