  • Page 3 1- Connectivity & Power Acid8 features 1/4” audio output, MIDI input/output, 1/8” gate/sync input/output and a power socket. Acid8 is equipped with a bridge rectifier so can be powered by any AC or DC voltage source of between 7v and 15v, 1200mA.
  • Page 4 2- Operation Overview Acid8 enables you to edit patterns and songs under three main layers: Step Mode At this lowest level you create and modify patterns, step by step. A pattern consists of 16 steps, but up to 15 of these steps can be skipped to form shorter patterns.
  • Page 5 3- Step Mode Activate step mode by pressing down the rotary encoder (all black knob) until the word Step is lit. At any time you can toggle between Step and Pattern modes by clicking the encoder again. Now roll the encoder to cycle through the 16 steps of your pattern and modify to your liking.
  • Page 6 You can also transpose each step across a 3 octave range using the & buttons. Acid8 can automatically advance to the next step when a note is entered. To toggle this feature on and off, hold shift, then press the encoder.
  • Page 7 3-2 Rest, Accent & Slide Set rest, accent or slide on or off using the respective buttons. The illuminated dot above the button indicates their status. Rest mutes a step. Accent boosts the filter envelope. The amount of boost is set by the accent knob.
