gribbly ADT

gribbly ADT implements Beatles/Townsend-style artificial double tracking (ADT). ADT is a thickening/widening effect usually used on vocals - but it can be used on anything.

gribbly ADT is a custom Combinator 2.0 patch for Reason 12. It uses only stock devices.

Instructions

• gribbly ADT is designed to accept a single mono input (e.g., a vocal).
• This signal is split into DRY, ADT1, and ADT2 channels.
• DRY channel is an unmodified copy of the input signal. You can set a fixed delay offset with the DRY DELAY knob (this allows the ADT signals to "get ahead" of DRY).
• ADT1 and ADT2 channels are identical. Each continuously changes the "tape speed" of a copy of the DRY signal according to the AMOUNT and RATE knobs, emulating a tape machine speeding up and slowing down (including both time and pitch changes) relative to the DRY signal. This is what creates the classic ADT effect.
• You can set a fixed delay offset for ADT1 and ADT2 with their respective DELAY knobs. Tape speed variation is applied relative to the fixed offset.
• The standard speed variation is a sin curve, to which you can add some randomness with the VARY button.
• ADT1 and ADT2 tape speed can also be manually controlled (see below).
• The TAPE section has controls for a tape simulation effect applied to ADT1 and ADT2. WARMTH rolls off top end by decreasing tape speed. TRIM adjusts the volume of ADT1 and ADT2 together. Turn the tape effect off with TAPE OFF.
• The MIX section offers level and pan controls for each channel.
• ADT2 is silent by default.

Usage ideas

• For a more "Beatle-y" effect, load the default combi and pan DRY and ADT1 hard left and right. Leave ADT2 level at zero.
• For a fuller sound, turn up both ADT1 and ADT2 in the MIX section, pan DRY to center, and pan ADT1 and ADT2 left and right.
• If you'd like to manually control the ADT "tape speed" (e.g., using a tempo-synced LFO), you can turn ADT1 AMOUNT and ADT2 AMOUNT to zero and control DRY, ADT1 and ADT2 via 'Control CV in' on the rear panel. Use a bipolar CV signal.
• If you want the ADT channels to get ahead of the DRY channel, increase DRY DELAY, and reduce ADT1 DELAY and ADT2 DELAY.
• For a crazy effect, try turning DRY channel all the way down (so you only hear ADT1 and ADT2), and turn ADT1 AMOUNT and ADT2 AMOUNT way up.
