One-Note MIDI Chords?

[stubbsonic]

I found a suggestion to Get Info on DP, run it in Rosetta Mode, and thus, the midiChords VST did show up in the instrument list. Got my hopes up for a moment. However, choosing it as an instrument caused DP (both DP 11.04 and DP 11.1) to quit unexpectedly.

I just found a plugin called Ripchord, which seems to have quite a bit of overlap with midiChords.

Works in DP 11.1. Had to turn on Multi Record. It has a cool feature where it works polyphonically, so you can overlap chords, but this doesn't work very well in DP as note-ons and note-offs trip over themselves and cause notes to get cut-off. It would be cool if it was more "intelligent" about that, but the fact that it even allows this is pretty interesting. With DP's weird issues with note-on/off prioritization, I wonder if this is unique to DP. I'll test in MainStage to see if that's the case.

Even with the various "strum" and humanize modes, it still scales velocity to the input note's velocity, which is good.

Wasn’t that changed a few updates ago? I recall a thread from the resulting mass confusion and panic.

OK, so I strongly suspect the issue with cut-off notes is due to DP's long-standing consecutive-note bug. Aaargh.

It's been described in detail in other threads. Briefly, in DP, if a first note ends and a second note begins on the same tick, the second note gets cut short. I suspect DP prioritizes playing the second note-on first, followed by the first note-off (hence killing the second note, regardless of its duration).

This is causing ripchord's cool overlapping chord function to not work correctly.

This DP issue has been around for years. It's a serious one, but they are in denial. What's the phrase? "MOTU must face..."

Sorry, your post came in as I finished up my last post. It seems like MOTU may have partially solved the issue, at least for playback, but I wonder if MOTU developers just came up with some workaround. For example, the bug still exists when scrubbing--- even very slow scrubbing. I used to use scrubbing as part of my compositional workflow, but had to reduce note-durations quite a bit for it to work right. I wish they would fix it properly.

The developer of ripchord says their plugin works as expected in all other DAWs/Hosts they've tested, and had not gotten any reports of cut-off notes before I mentioned it.

Yes, I remember that thread too. IIRC, I was able to get it to work properly if there was some space between the notes. As you say, not a solution -- scrubbing should not give you something different from playback.

I'm guessing it's some combination of hard to replicate, hard to diagnose and/or hard to fix. The fact that they were blaming third-party VI's for such a long time makes me think there's some complication that we don't know about.

BTW, Ripchord is freeware. Here's a quick rundown for how to get it to work inside DP:

1. In DP preferences, in the Audio Plugins section, you may need to enable the Ripchord VST, possibly clicking re-examine to enable it.

2. Create three tracks:
* a MIDI track,
* an Instrument Track (sound/playback)
* an Instrument Track (ripchord itself, the VST3).

3. Turn on Multi-Record mode (so you can select specific MIDI input sources).
This setting is in the Studio pull-down menu.

4. Set the MIDI track's input to your MIDI controller

5. Set the MIDI track's output to the Ripchord instrument

6. Set the input of the sound/playback instrument's track to Ripchord (channel=any)

7. Finally, you have to record-enable both the MIDI track and the sound/playback instrument. The Ripchord instrument itself, doesn't need to be play-enabled, it passes MIDI regardless.
