Here is an experimental patch if anyone is interested in playing a MIDI keyboard with split points such that the left hand plays “autochords” and the right hand plays melody, both in the set Meander mode and root scale, in this case D major. For this, only keyboard white keys are played and each hand should only press one white key at a time. For both left hand and right hand, the keys play the following circle degrees or scale intervals: C-I, D-II, E-III, F-IV, G-V, A-VI and B-VII or
C-1st, D-2nd, E-3rd, F-4th, G-5th, A-6th and B-7th
So, these are relative degrees and intervals, when you press the C key (for example) you will get the “I” chord degree or the scale 1st interval melody. If Meander is set to C-maj, C is C, but for D-maj, C is D and so forth.
To get a feel for this, I recommend playing via the left hand the Meander chord progression that is selected in the patch and is Pachelbel’s Canon in Dmaj for which the chord progression is I-V-VI-III-IV-I-IV-V
EDIT: Here is a corrected patch. Due to how the Harmony module works, I was playing a 3 note chord rather than a 4 note chord.
Keyboard Split with BASICally with Meander and or Squinktronix Autochord Harmony Template-1.vcv (13.4 KB)
By default, Meander provides the chord root note only to Squinktronix Harmony which follows the Meander mode and root scale. This Harmony 4 voice leading chord is played as well as arpeggiated by Squinktronix Arpeggiator as an auto-melody and the Harmony bass note played as an autobass part.
There is a lot to play with here, but you may want to keep this downloaded patch unmodified so you can go back to it is things get too confusing or messed up, which is easy to do in a patch of this complexity and strangeness.
For the curious, MIDI keyboard splitting is extraordinarily difficult to manage in a general case. Whereas Impromptu PART works great for playing a polyphonic (CV and gate) voice, I ended up having to use the BASICally scripting module to handle the split and send the left and right hand notes to different voice modules while operating in only a 2-channel MIDI polyphony setup.
Here is a zoom of the fully BASICally script. Part of the complexity is that this script uses 7 input ports for MIDI 2-channel CV, gate and velocity and keyboard split point and 6 outputs for left and right hand CV, gate and velocity.
While not needed to know to play with this, this patch takes advantage of Meander’s “octal radix” notation
