Is it possible to create a table that does not hold floats, but symbols, or even lists?

You can do it with data structures, but its not nearly as straight forward.

mpf... can you - briefly - explain, how?

Or, better maybe, I explain, what I want to do.

I want to "parse" incoming MIDI messages.

for example: a midi controller message (ctlin) of #99 (NRPN# MSB) on channel#15, followed by a cc#98 (NRPN# LSB) on channel#15, followed by a cc#06 (value MSB) on channel#15, followed by cc#38 (value LSB) should send a message "NRPN#(msb*128+lsb) value (valueMSB*128+LSB).

Thus, I need to store up to 4 ctlin messages and compare their cc# for the right order (99, 98, 6, 38) and wether they are send on the same channel.

I did this using [ctlin]-[pack f f f]->[list-prepend]->[list-split]->feedback to list-prepend, so an incoming ctlin-messages is stored in the first place of a "buffer" of 4 ctlin-messages, whereas the previous ctlin-messages are shifted right out of the buffer.

problem is: the ctlin-messages could be send with different channels, so that a "NRPN-message" (cc#99,cc#98,cc#6,cc#38) could be interrupted by another cc# on another channel.

So, I need to have a buffer for ctlin-messages of each MIDI channel, and not only one buffer for all incoming ctlin-messages.

Now, if I could store lists per channel in a table of lists...
