I have a program set up this way

PAD
2: BD
3: HH
4: OH
6: SD

9: Sample1
10: Sample2
11: sample3

13: Crash
16: Crash

The program is set to poly and i can play drums and sample at the same time.

However, i went on to record a sequence where sample1 plays from beginning to end while the drums plays, but when i have 3-4 sounds playing at the same time, the sample stops playing...

I haven't set any pads to mute the sample except that PAD9 mutes pad9 and pad10 and PAD10 mutes pad 9 & 10.

But why would the sample stop playing when I'm not playing PAD9 or PAD10?

Is there a polyphony max voices?

32. make sure the pads containing your long samples are set to MONO. also, trim the dead air off the end of your samples.

But if the sample is set to mono, the sound is mono as well...?

I want the sample to play in stereo!

If you have a stereo sample:

When in PROGRAM mode, SAMPLE tab, SOUND column is where you can set the sample to play either in: stereo, L, R or L+R.

Now where you can change the sample to be either poly or mono is in the AMP tab, VOICE column.

Cool, i'll try it when i get home from work :-)

Edit: But I'm still wondering why changing a sample from ST to MONO in pgm mode would fix the problem, and does anyone know why the problem occur, I mean, the technical aspect?

Nym was talking about making sure it was set to MONO and not POLY in the in the AMP tab, VOICE column.

In the Akai OS manual, look for: Limiting the number of the voice in the Program. It's all there.

RTM.

Worked like a charm :-)

I read page 85 - 86 like you said, but I still don't know WHY it would cancel a sound on a totally different pad?
By dtaa pla muk Fri Jan 18, 2013 4:39 pm
because you've reached the polyphony limit. the oldest sample playing is the one that gets cut off by the new voice.

in os128xl you can set a per-pad polyphony priority.

Maybe some samples were set to MONO and not POLY.

Look in the AMP tab, VOICE column.

The way it works is by PROGRAMS. All the samples set to MONO (monophony) in a given program will cut the other samples off in that same program.

That is why i make programs especially for my drums and i make other programs for my other samples. I keep them separated and well organised.

I want all of my drum samples to be POLY (like a real drum), so they don't cut each others off. Except maybe for the hihat, where i want the closed one cutting the opened one off.

For all the other samples, i generally keep them in MONO so they do cut each others off. It gives me more control over what is playing/not playing. I later make adjustments if needed.

I'm actually experiencing sound cancelling when Im hitting 26 voices or above, so I'd like to know how to count the voices so I can figure out where it goes wrong!

I've just tested a program where the setting is

• Play: Mono
• Voice Mono
• Release: 0

...and with 7 Stereo samples I'm STILL able to get voices up to 16.... how the f**k can I squeeze 16 voices out of a program that only have 7 ST samples (14 voices) and EVERYTHING is set to mono and there's 0 release and no effects? I mean, i shouldn't even be able to get it above 2 voice when the program itself is set to mono?

I really don't get it :-/ ?

Edit: When I'm "squeezing" out 16 voices its by hitting the 7 pads at once, but still shouldn't be possible when the polyphony is set to mono?

If you're referring to Pad10 [Other] Voice Monitor, then yes, that's how I know how many voices I'm using.

OK, I believe you man :) Maybe reset your unit (hold 'erase' key while powering on and hold it until you see main screen).


Than check again all settings (jog wheel is sometimes very sensitive and it can easily switch before you close some window).
Make sure it's MONO in upper right corner of program, and doule check all pads (shift + F6) are set to MONO voice overlap as well.

Than, record a sequence with it, using many pads at once, just some random knocking. Just this ONE program. OK?
You got a sequence? Press play and..

.. take a look at voice monitor.. it should be not more than 2 voice on monitor.. I'm talking about 1-channel samples (if you got stereo it will show 4)

If it's showing more than 2.. (or 4Stereo) check ADSR as you already mention it, and turn down release and attack to 0.

Than come back and tell me it's still wrong.. j/k hope you will sort it out..
