Helpful Glitches

Adding Delay plugs to the Tape track and Tape plugs to FX1/FX2

This will allow you to create layers of the delay effect, multiple tape layers, etc. THIS WILL CAUSE YOUR OP-Z TO CRASH EVENTUALLY AND IT MIGHT BE VERY LOUD if any project on the device has this glitch enabled, even if it's not the active project.

You use the same glitch regardless of plug/track. Here's how you'd add a delay plug to FX2:

1. Open the app and enter Configurator mode
2. Change the active track to FX1 and select the plug that currently has the Delay engine
3. On the app, drag the Delay plug icon slightly to the side and hold it there with your finger
4. While still holding the Delay plug, change the OP-Z's active track to FX2
5. Place the Delay plug onto the slot where you want it to go
6. Commit the change

You can use this to move samples between drum and synth tracks, but it mostly causes immediate crashes or harsh noise. I've gotten a drum plug to make sound on a synth track but it sounded awful to the point of being unusable.

Adding a new preset slot to a control track

I started using the Motion track to store settings for an external synth. The problem is the Motion track (Track 16) only has 1 plug, meaning you only get 14 presets... unless you're like me and are determined to break the device.

Here's how I added an empty plug to Slot 2, giving me a second set of presets on Track 16:

1. Navigate to an audio track (Tracks 1-8)
2. Clear the existing sample/plug from Slot 2 by holding track and the slot number
3. Start to add a blank sample to Slot 2, but....
4. ...change the active track to Track 16 before it's finished

App shows a flat line when opening up a sample in sample mode (+ workaround)

This is annoying but fairly easy to correct by simply opening up another sample plug. In my experience, it will take a second before displaying the amplitude of the second sample, but once you re-open the first plug the flatline issue should be fixed.

1. Close the current sample
2. On the same track select a different plug that contains a sample
3. Enter sample mode and wait for the sample to display
4. Close the current sample and re-open the original sample

Dramatically reduced resolution at Step Length 9 (no workaround)

Setting Step Length between 1 and 8 yields a similar resolution for recorded notes. Step length 9 (16 bars) does not. When a track's step length is set to 9, a note held even slightly longer than one step will be last two full steps.

To test this, I used the following procedure:

1. Make a track on OP-Z with 5 patterns.
2. Change the Chords track's step length in each pattern to 1/2/4/8/9
3. Add a track to REAPER that plays a note that's 5/4 the step length then advances to the next pattern
4. Record MIDI from REAPER onto OP-Z
5. Record MIDI from OP-Z to REAPER
6. Compare note information

I got the following results:

Step length 1: +0.0.03 (0.0.31 vs 0.0.34)

Step length 2: -0.0.01 (0.0.63 vs 0.0.62)

Step length 4: -0.0.02 (0.1.25 vs 0.1.23)

Step length 8: -0.0.02 (0.2.50 vs 0.2.52)

Step length 9: +~1 measure (1.1.00 vs 2.0.91)

Presets don't sound the same when you load them (+ workaround)

OP-Z doesn't consistently load the last parameter page for presets--i.e., if you saved specific FX send values, panning, and volume with a preset, it will only sometimes load those values when you load the preset.

If you load the preset before adjusting any parameters on last page of that track, it should load the last four parameters exactly as they're saved with the preset. If you've already altered the last page, loading the preset will not affect the last parameter page.
