Answers to Frequent Questions

If you discover a problem in your MPC3000, we would appreciate it

if you would please read the relevant section of the manual to make

sure you correctly understand the operation before you before call

your Akai representative. Here are some answers to commonly

asked questions and problems:

When I play a particular sequence or song, the timing is irregular.

What’s wrong?

If you notice a timing irregularity in song mode at the point of

transition from one sequence into another, the problem may be

caused by assignments of the Program field (in the Play/Record

screen) for the new playing sequence. When a new sequence is

encountered in a song, any program assignments for the tracks in

the newly selected sequence are sent out at the moment that the

sequence starts to play. This can present a problem because most

synthesizers require time to change programs, which can cause any

notes existing at the start of the new sequence to be delayed. This

delay is brief in most synthesizers, but is usually enough to cause a

timing irregularity at the start of the sequence. To avoid this prob-

lem, remove any assignments of the Program field for all sequences

except the first sequence in the song. If you are encountering the

same problem when changing sequences while playing (in which

case the new sequence begins immediately following the current

repetition of the current sequence), then use the same solution:

remove all program assignments for the newly selected sequence.

If the timing irregularity does not exist at the beginning of a se-

quence, it may be due to the sequence containing a large system

exclusive message at that location, in which case the MPC3000

must finish processing the system exclusive message before playing

any other notes at that location. If this is the case, erase or move the

system exclusive event that is causing the problem.

If the timing irregularity does not exist at the beginning of a se-

quence and is not due to a system exclusive event, it may be due to

having too many notes (more than approximately 10 or 12) at one

tick in the sequence. If so, this could cause the last notes occurring

at this location to be delayed. This problem is aggravated at faster

tempos. This problem exists to some degree in all sequencers, and is

due to the fact that there is a finite number of notes that the inter-

nal computer can process at one time. However, this will NOT cause

the sequence to slip out of sync when syncing to an external sync

source. To reduce the processing requirement in your sequence, try

the following:

1 2 ... 229 230 231 232 233 234 235 236 237 238 239 ... 275 276
