Thanks for your reply. Your mathematical analysis indicate that there is some other problem. I am a poor piano player, and mostly just hit one 4-note chord per measure. Using cakewalk I noticed that the size of the piano track was over 10,000. If these are all notes, then that is over 250 per measure. There is no way I could play that many even if I wanted to. I will try to determine if there is controller data that were inadvertenly included in my sequence. Thanks for the help.

First: No, the number of tones in each patch has nothing to do with the capacity used in the sequencer. The sequencer just sends a note over the correct MIDI-channel, and it is up to the synth-section of the XP to actually produce the sound. It does not matter to the sequencer if the sound produced is simple or complex.

Another thing to remember is that the sequencer stores 20000 MIDI-events, and not notes. This means that if you hava a lot of controller-data, sysex, program changes etc, this will use up the sequencer capacity. One prime example here is the aftertouch. If you press a key and make a long sustained note while changing the aftertouch pressure, the sequencer will only record one note-event, but perhaps hundreds of Control-Change-events for the aftertouch.

Data thin helps. It reduces the amount of controller data. This will not normally be audible, but the sequencer capacity is extended. If you are having problems with sequencer-memory, try to use data thin on each track after you have recorded them.

Another trick is to switch off aftertouch on parts where you don't need it, so that you are sure that no aftertouch-changes are generated.

Hope this was understandable.
