NEW: Use keyboard split to set the filter.
NEW: Auto Latch mode keeps the filter active between chords.
Set a scale filter on the fly. Notes will be quantized to the scale. The filter can be set either by sending notes on a specified channel, or by sending notes below a keyboard split point.
• CTRL knob: set to SPLIT or to a MIDI channel. If set to SPLIT then the next knob sets the MIDI note below which will set the filter notes. If set to a MIDI channel then all notes on that channel will set the filter notes.
• QUANTIZE/PASSTHRU:
• Quantize: Force notes to the filter. If the filter is empty, notes are blocked.
• Auto: Quantize notes to the filter. If the filter is empty then pass notes through un-quantized.
• PassThru: Ignore the filter. Pass through all notes un-quantized
• LATCH:
• Latch OFF: Only held notes activate the filter.
• Latch ON: Keep adding notes until Latch OFF is set.
• AUTO: Add notes as long as more than one note is held down. Don’t remove the notes after release. Once the held note count reaches zero, arm for a new chord. Replace the filter with new notes once one or more notes are held down again.
• NOTE: Moving from Latch ON to Latch OFF clears the filter even if control notes are held down.
• Tap the SHIFT button to send a MIDI Panic on all channels (See NOTE)
NOTE: This script assumes proper Note-ON/OFF behavior of what is coming into it. There’s only basic stuck note prevention.
NOTE: Tapping pads does not set notes, only playing notes on the control channel does this. See Simple Scaler on PatchStorage for screen-interactive custom scales.
Thanks for making this. So far after a few minutes testing it does everything I thought it would. Iam using scaler 2 for chords and Helium for the melody inside of Logic iPad and so far works perfectly. Really a great time saver , rather than having to edit Midi by hand for every chord change. No stuck notes so far, timing is perfectly on. I’ve been looking for this a long time, Many thanks again
Great @plopseaw! Thanks for letting me know it works.
V0.3 adds a Latch knob. While set to Latch, notes are added to the filter until latch changes to OFF at which points the filter is cleared.
v2.0
* Adds the ability to set the note filter using a keyboard split rather than a separate midi channel.
* Adds an Auto Latch mode that preserves the filter between chords. The filter will “stick” even if you release the notes. The next note will clear the filter to start again.
v2.1
* Now passes notes that set the filter through.
