Please allow for unlimited instrument and MIDI tracks in all versions of Pro Tools. For composers running enormous Vienna Ensemble Pro templates this is essential. Avid would be crazy to not allow for this — I'm sure many others like me would prefer to not have to jump ship for Cubase or other DAWs that don't impose arbitrary track limits.
Simple as that. Currently Pro Tools is limited to 4 sets of 26 groups - 1 group for each letter of the alphabet, 4 times over - or 104 in total. For large post production sessions (especially when working with 'multiple mono' tracks), this really isn't enough. Would dearly love to see this limitation removed
