Watched the videos and as a sequencer, this would be really great. Perhaps not as many midi outputs as I'd need, but still, really great workflow - flexible note editing with zoom functions are really cleverly implemented.
For sampling - yes, looks pretty capable, if a bit basic. Editing with 4 character screen is starting to be a bit problematic.
For synth... it looks horrible to try to menu dive and edit the options. I guess I'd never do anything else than edit ready patches a bit with that interface.
Still tempted to get this, mainly for sequencing hardware gear. I have Beatstep Pro, but I pretty much hate it for anything other than basic modular gear drum sequencing. Deluge would look ideal for hardware drum sequencing, but unfortunately you cannot set individual lines so that they'd have configured the midi channel and/or note the way you'd like. Asked about this by email and got this answer:
Within one drum track, you cannot output to separate MIDI channels / notes (you can set up to 4 rows to output to the gate outputs though). To output drums to MIDI, you'd have to create a separate MIDI track for each MIDI channel you wish to output to, then scroll vertically to the note-code you wish to output.
Does that help? We'll have our manual online soon...that might make things clearer.
