====== TIPS AND TRICKS ======
===== Secret Drum Programming Tips =====
Jim Pavloff [[https://forum.audiob.us/discussion/comment/731474/#Comment_731474|advises]] : “holding down the Step Edit button in the Drums section, you will be able to edit additional 16 steps (backbeats)? Backbeats are steps which shifted forward by a half step between the main 16 steps.”

@lorichs [[https://forum.audiob.us/discussion/comment/1011589/#Comment_1011589|also mentions]] : "Another one on the drum machine. Go into step mode. Hold down the desired step. Now spin the dial to the left to set up step conditions."
===== MIDI Mapping =====
Most controls in the app can be controlled via MIDI. Pure Acid has MIDI Learn capability to override the default mappings.

==== Default MIDI Mapping ====
  * 7 = Master Vol
  * 8 = Bass Vol
  * 9 = Drum Vol
  * 12 = Env Mod

  * 16 = Accent
  * 17 = Distortion
  * 18 = Drive Bass
  * 19 = Drive Drums

  * 91 = Bass Send FX A (?)
  * 92 = Bass Send FX B
  * 93 = Drums Send FX A
  * 94 = Drums Send FX B

  * 71 = Resonance
  * 74 = Cutoff
  * 75 = Decay
  * 76 = LFO Rate
  * 77 = LFO Depth

  * 85 = FX A Param 
  * 86 = FX A Param 2
  * 87 = FX A Param 3
  * 88 = FX B Param 1
  * 89 = FX B Param 2
  * 90 = FX B Param 3

  * 102 = MFX X
  * 103 = MFX Y
  * 106 = MFX ON/OFF

  * 104 = Pitch

**Pattern-changing via MIDI**. The bass synthesizer and drums accept MIDI program change 0 through 11 to select patterns 1 through 12. Send program change on MIDI channel 1 for bass patterns and MIDI channel 10 for drum patterns. The change happens when the current pattern completes which is just like the buttons.
