I suspect @jamieh captured your question more accurately than I did so I hope you got what you needed.
Your question triggered some curiosity on the topic and a couple other things surfaced for that might be helpful to you or others.
As for reversing a sequence of single notes and using the DAW tempo for playback, other than @jamieh’s suggestion of editing the chords down into individual notes w/in a pattern, another way I found to hear the individual scale notes is by setting the Perform mode to Arpeggio with a 1/1 timing and playing the chords from a Scale. (This might be a duh! for some, but not me) If you want to reverse the notes, you can create a pattern with those chords and same Perform setting.
Aside from editing the chords down to single notes while in the chord editor, you can also save a chord into a chord set and then edit the resulting XML file to keep only the root notes. It is a very simple, albeit tedious process that I can’t at the moment see a need for, however thanks to Scaler’s clean use of XML, it works well. I’ll spare you the details, but if curious just ask. However, there are a couple fast and simple workarounds that might prove helpful and surprising.
MIDI Capture / MIDI Detect and roundtripping through Studio One. (and other DAWS)
MIDI Capture will record the notes from the Scales Audition feature and anything else you play…tested to thousands of bars. (I use it as a retrospective record when I’m toying around in Scaler) After recording the MIDI and dragging it into S1, I can quickly reverse the notes by using the Mirror Notes functions in S1 (you can find it on the S1 Music Creation Toolbar) . If I want to play those single notes w/in Scaler I can immediately use the Scaler Detect Midi feature (using the same instance of Scaler) to load them back into Scaler as detected notes.
While I can’t move them into an editable chord set directly, l can play them back using the DAW tempo, randomly with my bound keyboard or within a Scaler Perform mode. The whole process of dragging out and then detecting back into scaler is about a 15 second round trip.
So while not a native solution, it might be an easy work around (depending on your objective) with some cool added benefits. For example, while exploring this topic I used this approach to create sets of scales and chords playing sequentially to help me with ear training. In just a few minutes and with little effort I had a bunch of useful training material.
I’m not a competent keyboardist so I’m always looking for inspiration and quick ways to create interesting progressions, melodies, etc. When I cycle Scaler output through S1, I can use all the S1 creation tools like randomize pitch w/in scale, chord creation, etc. to generate MIDI that I can then bring back into Scaler and keep exploring. Between the two environments, the creative possibilities seem limitless and the process is dead simple.
Also, don’t overlook Keys-Lock - depending on what you are trying to do, it has some pretty helpful features.
Thanks for posting the question…it prompted me to dig into yet another area of Scaler that I had not really explored.
