Thanks for replying. I have been thinking about the mc909 to give you a good answer. The ergonomics are good, I am able to gradually figure it out and get good use out if it without knowing everything about it which is important. And things are arranged well.
The midi timing is basically as good as I can be, in and out.
The mute and fader setup is a great help for live tweaking. I wish all the tracks could be addressed at once but they are stacked 8 on 8.
The recording is very straightforward and the only negative is the inability to record over the running pattern and overdub, and this indeed is one of the things that make me look for other companion pieces.
This may sound weird or naive, but the sounds and drum sets are a huge asset. I think this opinion is very peculiar to me at this time. I have spent many many hours crafting sounds, and there was a period when I thought sound was superior to music. But now I love many, by no means all of the sounds. I really like having credible drum sets that have some genre and sonic identity, without having to hunt for them or make them. In most of the songs I have been working on, the beginning sounds rarely are the ones thst survive, and they are mostly replaced with sounds I make on external synths, but the ease of dialing through many different patches so easily to fit a part I played in is a huge productivity boost.
Edit - the fact that these sounds largely Hew to obsolete genre conventions is a plus. I have gigabytes of modern sounds on my ROMplers and vsts etc, but somehow the cheesiness of a lot of old sounds is reduced when their context fades away.
I like that I can visually edit patterns, though it is not as easy as the DAW.
I like the quantization options, but don’t like that they are batch based.
I like the real time parttern feature. At the right time during a jam I can play that with one hand and keyboard with another. Having fixed options at hand thst have been preselected to match the song, and indeed might be samples of the song, really helps reinforce the theme with little performative effort.
The pads are pretty good, not as finger drummy as I would like but they make up for it with their expressiveness.
I can’t articulate the final thought but somehow this creaky and increasingly obsolete groove box is the best all around quick composition tool I have found besides the DAW, with a big difference being that I can spend all my time standing up. I still use the computer, but not always, and it is not necessary since I now record to multitrack on sd card instead of to the computer, and then I suck the stems onto the pc after the fact if warranted.
