it is a property in the MPC1000 program itself.
so if you are triggering bass samples on the MPC, make sure to increase the decay time.
To do so (if I remember correctly, the box is not in front of me):
. MODE > PROGRAM
. tap the pad where the bass sample is assigned, you should see the sample listed (4 slots)
. move the cursor to the LEVEL column (volume... default is 70) on the bass sample
. press the WINDOW key (which gives you more options related to the LEVEL
. you can now set a few ENVELOPE parameters (Attack, Decay, etc)
. Set the decay time so it sounds good; tap the pad a few times while you change the number
Note that this is useful with any sample which have a loud end or beginning, especially in the bass range, from my experience.
I hope this helps
I will probably explain some of this in a tutorial on building PROGRAMS.
