My list of preferred features so far:
1. Accept external midi clock
2. Ability to freely assign outputs to track, like on the monomachine (AB/CD for stereo or A/B/C/D mono)
3. Midi implementation chart published so I know which midi cc number belongs to which parameter
4. seq transpose the way it is implemented on the monomachine (with the FIX option to exclude tracks from transposing) I'd love to be able to make samples pitch through midi.
Without doubt there will be more I'd be wanting
oh yes and 5. password / pincode protection to prevent my girlfriend from sneaking away with the octatrack
