The PA3x already has almost every triggerable option hardwired on the front panel already!

The real trick with CS apps is to be able to chop off the live input at the 'Play' boundary. In other words, if you are still holding down the chord, as far as the CS app is concerned, it ends at the bar boundary.

A CS has a few significant differences to a sequencer. On the one hand, it's really only ever dealing with one channel's input (the NTA channel) and outputting one channel, but it has to do a little bit of housework to tidy up the input once the loop is determined. And with a CS, the loop length isn't decided until the users SAYS so! But I still don't see how it wouldn't be anything difficult for someone capable of a normal sequencing app.

I once tried to find out whether Ableton Live could be used, as it has a live audio looper, and MIDI capability, but I could never get a response from Tech Support or the forum. Anyone know a Live 'power user'?

No midi support of this type until Live 9 afaik DIki. I currently have live 8, but have never really used it apart from doodling, for this very reason. I am waiting on 9 to be released so I can upgrade.

Live is part of my new "strategy" re playing "style" type backing tracks, but not using styles per se...

Keep me posted, then Dennis. As soon as it can loop MIDI like it loops audio, we are good to go.

Sure will

I also think you are seeing where I am going with this too Cool!

I am now adding the Chord Sequencer to vArranger.

Diki. Is 2 buttons are OK?

One for REC and one for PLAY?

You really need three. Record, Play, Stop.

Then there are other considerations, like if you play anything in the Chord Recognition area, does it get ignored, does it get added to the sequence, or does it over-ride it..?

TBH, as well as adding it to vArranger, a simple standalone app that would do it to incoming MIDI and simply spit out the sequence on a User designated NTA channel would, I think, sell very well to people that already have hardware arrangers...

Why 3 buttons?

The Record button, can be pressed again to stop the recording
The Play button, can be pressed again to stop the chord sequence, and give back the control of the chords to the player.

In my view, if you play in the chord recognition, while the chord sequence is currently playing, it get ignored, but play the left hand sound .

That's the way Roland did it, that's the way Korg do it. I guess, if you wanted to, one button could do it ALL, with double taps. But it is simpler, and less confusing, if there's a button for each function.

Generally, you hit Record to start the recording, then you hit Play to go into the loop. But if you need to play a bridge or something before you need the loop, you hit Stop. Then you hit Play when you needed the loop. And either Record to start a new loop or Stop if you wanted to go to you being in control.

Mostly, and with screen real estate being a non factor, I'd go with what is the simplest route. Plus, it's what they are used to doing.
