When I hold down the roll button or stack more than one drum sample on top of another I get an uwanted flanging effect when I hit the pads. This does not happen all the time but it is annoying as hell. Do you think this is a software issue? I damn near ready to send this jone back to Akai. Give me some feed back.

it is where your hits are landing, if you put the same sample close together in poly mode it will flange.

change the sample to mono or be careful where you put your hits.

funny, i was jus gonna post a thread on this tonight.. lol.. but yeah

i get the same when i layer the same drum up twice on the same pad (for a volume boost.. really gives it an edge and makes my drums really bang) however.. about 10% of the time it flanges.. all the mpc is doing is playing the exact same sample at exact same time... yet it flanges at random times?.. quite annoying...

is it really on the same tic? it needs to be on separate track to be on the same tic.

just boost the volume or use the compressor if you need the extra bang.

elmacaco - I think he's using layers, so by definition it *should* be on the same tic.

As for the flanging...it's called a "comb filter". The akai can't get around it...it's software based like anything else since 1980, and it just can't do exactly more than 1 thing at a time. So your 10% of the time problem won't go away, but keep it in your bag of tricks for when you do want it (just deliberately trigger the same sample more than once really close).

If you play two copies of a sample at the same time they will often flange. Flanging occurs when audio is mixed with a slightly delayed copy of itself. If you have two drum hits of the same sound and they are slightly off it'll flange. Even if it is on the same tick, it may flange due to small delays in the computer circuitry. It is sort of hard to explain but there are propogation delays of the electrons in the circuitry. It takes a finite amount of time for electronic signals to travel therefore things aren't going to play at exactly precisely the same time.

aha.. i understand now.. tiny amounts of latency mixed with processing time makes the triggers so slightly out of exact sync that they flange... gotcha..

also found a work around tho.. record the sample when it hits and works without flanging (to a comp) then send it back to the mpc as a single sample.... or yeah.. use the compression to get the boost... just find it easier to layer em..

Thanks though.. cheers for the help :D
