Exchange tips and tricks for the Akai MPC4000
By grassroots Thu Feb 16, 2006 12:43 am
Hey, was thinking about asking a question today and this is kind of related...

Q: Has anyone heard of an AKai unit cal the SG01 that is a vintage sound module. I still actually haven't got round to buying a midi keyboard, but can get one of these sound modules cheap 2nd hand. I was considering buying a Juno or Jupiter cause I like analogue synth bass sounds and am not as technically minded as the rest of you (ie. don't see myself downloading sounds and modulating them or whatever).


Any advice appreciated. Cheers

tell me about it.... Moving to the mpc4000 from the QY700 that *IS* my #1 beef! Everything else is way better on the MPC but that alone has made the transition less then perfect. Otherwise a great machine....

The Rapture plugin comes with hundreds of single cycle loops in wav format which you can use as oscillators in the MPC.

Any one have a link or cAre to teach on how to take Cingle cycle up in tune, but avoid aliasing? There is a way of re-sampling in different sample rates to do this, but I don't know the pArticulars. Anyone?

Thanks,

Charlie

Band Pass filter! or 12/18db LP filter (with no resonance) where the aliasing is occurring. At first it will sound way to filtered but tweak it a bit and you can find a good range. If you can filter the cycle before you use it as an oscillator that would be the best possible solution, much easier to stop it before it starts.

Thanks for the answers so far, but I was referring to a method of resampling in different sample rates to change pitch.

:shock: :hmmm: single cycle not be enough. :hmmm: :shock:

BUMP!!!

Turn on my MPC.
Press mode + pad 5 ( Go to Record )
Select: Analog Input
Press press F6 ( Start Record a few seconds/moments for sample1 ) = Recording Noise for sample1

Image

Ok

Go to Trim mode ( mode + pad 6 )

With sample1
EDIT: Normalize 100% for example.


ImageImage

Now
use extract for obtain sample2 ( half of single cycle wave) and sample3 (other half of single cycle wave)

Select containing wave start point for 00000000 and end point 00000001 = extract for obtain sample2

Select containing wave start point for 00000000 and end point 000000001 = extract for obtain sample3

Ok ?!!!

Now
Go to Trim edit Combine A + B


Image



Image

Sample2 + Sample3 = sample4 = SINGLE CYCLE

Sample2 + Sample3 = Sample4 = 00000002 end point ( lenght of the sample, view on TRIM mode )

Image

Sample4 + sample4 = sample5 = 00000004 end point
SINGLE CYCLE + SINGLE CYCLE = TWO CYCLES

Image

Sample5 + sample5 = sample6 = 00000008 end point



REPEAT SOMETIME
Sample.... + sample........ = xxxxxxxxxx end point

Sample.... + sample........
= 00000016 end point
Sample.... + sample........
= 00000032 end point
Sample.... + sample........
= 00000064 end point
S
= 00000128 end point
S
= 00000256 end point
S
= 00000512 end point
S
= 00001024 end point
S
= 00002048 end point
S
= 00004096 end point
S
= 00008192 end point
S
= 00016384 end point
S
= 00032868
Sample18 + sample18 = sample19
= 00065736 end point


Image

Now, select sample19 start point 00000000 and end point 44100 and discard ( trim edit )


The result is a sample with 22.050 hz (-herz-) CYCLES per seconds, you see this TONE/NOTE is square Wave, also Sine wave is very possible , other TONES/NOTES and much more!

Now, you know it!!
We can make a WaveForm with.... :roll:
