The maximum number of instruments per program is 16. There is no limitation on the number of any given type of instrument if you spread them among all avalibale programs. The only limitations are created by the note ranges of the instruments. Something is likely wrong with the construction of your SEQ (such as 1:inclusion of messages which cannot be properly processed by the libraries, such as aftertouch; or 2: perhaps you are placing time crucial messages ot the same delta time. Sometimes smf2seq processes these in the reverse order, causing playback problems. Always place one delta tick between time-crucial messages. What's a time crucial message? Let's say plyback is currently processing program 0 and you want a note on from program 1. The switch to prgram 1 is time-crucial. Lastly, 3: you may not have your instruments in the correct program. Those are the three most likely bad SEQ problems) or of your VAB. Double check everything. You can always post your VAB and smf/seq here; I won't be able to look at them immediately however.
