Gridlab Polygome: Fix Record Mode.

[monkey5an]

Summary

When using polygome in record mode, I want consistently accurate feedback and behavior for origin and step record operations so that when I trigger a recorded pattern it starts where I expect and plays the full pattern I expect.

• I want to be able to record a pattern where the relative offset from the first step is 0,0 so that I can trigger a pattern to start from the very note in the grid I used to trigger the pattern.

Steps

1. Download Gridlab and place in Ableton user library under Presets>Max Midi Effect
2. Load instance of polygome in MIDI track.
3. Connect a grid (monome256 in my instance).
4. Choose a pattern to edit from the top row of buttons.
5. Enter record mode by pressing the second button in the top row.
6. Observe recording message in M4L device interface -- "waiting for origin 1"
7. Press the grid button that you want as the 'home' from which each of your pattern steps will be offset.
8. Observe recording message in M4L device interface -- "recording x" (where x is the name of the currently recording step).
9. Press grid button representing note to record for the step.
10. Confirm device is recording the next step (x+1).
11. Repeat until pattern is complete.
12. Press mode button (second button in top row) to cycle back to play mode.
13. Start live playhead and trigger pattern by pressing a key.

Desired Behavior

• The new pattern should begin playing back using the correct offset from the 'origin'/home that was entered during record mode.
• If the SAME grid button is used to set both the origin and the first step of the pattern, then the pattern should begin playing back directly from the grid button used to trigger the pattern, with no offset.

Actual Behavior

• Device does not consistently ask for an origin when entering record mode. Instead, it sometimes simply says 'recording'
• If origin and step 1 of the pattern are represented by the same grid button (pressed twice during record mode: once to set origin and once as first step), the pattern does not play back as expected, with the pattern starting exactly on the grid button pressed by the musician to trigger the pattern. Rather, the last step entered in the pattern will typically be used as both Step 1 and Step 8 (in an eight-step sequence)
• The result is a very confusing and unpredictable interaction with record mode.
