  • Page 5: Mode Switch

    Metronome (Click Track) Mode Switch Function Buttons...
  • Page 6 Mode Switch The Mode Switch is the master control. Use it to choose what the Keypad and Tuners do. The Mode Switch also works as an Undo for edits. While the EDIT LED is ashing, simply turn the Mode Switch to any other position, and any edits in progress will be discarded.
  • Page 7 Tuning the Keys 2TAC’s V/OCT outputs are quantized in steps of 1 semitone equal temperament, or 0.083 volts. The pitches of the notes in your sequenced patterns can be adjusted with the Tuners (rotary encoders) above the Keys. Tuners 2TAC has a tuning range of about 5 octaves. The voltages at its V/OCT outputs can cover the range of 0 to +5 volts.
  • Page 8 Transposing Patterns To make melodic composition more facile, you can easily transpose patterns. Tuners Each pattern key has its own tuner, so you can transpose patterns in the background while another pattern is playing. 2TAC’s transpose function can’t make its V/OCT outputs go beyond the range of Keys 0 to +5 volts, so if you apply large transpositions to a pattern, the melodic relationship between its notes will be affected.

  • Page 9: Pattern Playback

    Track Cue The CUE buttons are used to mute / un-mute the tracks during playback. When a track is muted, its CUE LED is dark. But its patterns continue to count in the background, preserving the position of the downbeat. Use the CUE buttons to insert drop-outs, fills, or to add white space or silent sections to your compositions.

  • Page 10: Audible Indicator

    Click Track (Metronome) 2TAC has a built-in audible metronome function. Tap CLICK to toggle the metronome On and Off. The metronome automatically shuts off when you press the Stop button. The metronome’s rate can be set to divide the clock by 1, 2, 3, or 4. The default on power-up is divide-by-4, or quarter note beats if the clock input is considered 16th-notes.
  • Page 11 Pattern Chains Patterns can be linked together into chains up to 32 patterns length. A Pattern Chain can play through only once and remain on the last pattern in the chain. Or, you can make it repeat as an endless loop. Pattern Chains can be programmed any time, whether the transport is playing or stopped.
  • Page 12 Temporary Loop Points You can change the loop point of a pattern to make it shorter with Temporary Loop Points. Clearing a Temporary Loop Point restores the pattern to its original programmed loop length. This feature lets you add variation to your patterns without having to edit them. This function is only accessible with the Mode Switch on KBD1 or KBD2, and while the transport is playing.
  • Page 13 Pattern Tools 2TAC includes useful functions for copying, time stretching, rotating, and modifying patterns. Turn the Mode Switch to PTN 1 to modify Track 1’s patterns. When the Mode Switch is set to PTN 2, you can affect Track 2’s patterns. * The Stop button has alternate functions in Pattern Tools mode.
  • Page 14 Pattern Write - Real Time Edit You can record a pattern in real time by performing the events on the Keys. Your live input is quantized to the grid of the clock input. To write a pattern on Track 1, follow these steps: First, select the pattern you want to edit.
  • Page 15 Pattern Write - Step Edit This feature lets you edit a pattern step-by-step for finer control of the note data. There are two types of note events: Trigger and Gate (Tie). Trigger - Back-to-back Trigger events make a series of On-Off pulses at Gate Out, re-triggering the synth’s envelope generator. Gate (Tie) - Gate Out remains on steadily during back-to-back Gate events.

  • Page 16: Memory Bank Select

    Memory Bank Select 2TAC has three memory banks for pattern storage. The actively selected memory bank is indicated at power-up by a ashing LED over Key I, Key II, or Key III. After switching memory banks, any Pattern Chains will be lost. To power cycle the unit, unplug the DC Input from the back of the unit for several seconds, then plug it back in.
