Page 2: Overview
1. Overview Duophony is our take on the ‘Parallel Blender’ pedal. What is exactly a ‘Parallel Blender’? The idea is really simple: a pedal that blends the signals from 2 or more sources. source 1 source 2 output source n In the context of musical instruments, why would one want to mix sound sources like this? In most cases it comes down to ‘effects’. - Page 3 With Duophony, we extended this basic concept of parallel signal blending and pushed it to its full poten- tial, allowing users to seamlessly integrate this parallel blend device into their effects chain and get the most out of it. Here’s a simplified block diagram of the Duphony’s internal signal paths and processing for your reference.

2. Controls MIX CONTROL: Duophony sports two rotary touch sliders that are used to control the blend between Loop X and Loop Y. Sliding clockwise will give Loop Y more proportion in the mix, and sliding counter-clockwise will give Loop X more proportion in the mix. - Page 6 DRY LEVEL CONTROL: Duophony also has the ability to blend in the clean (dry) signal into the mix. DRY LEVEL control is used to set the amount of dry signal passed into the mix. As with the Mix control, the upper slider controls the dry level for Left channel, and the lower slider controls the dry level for Right channel.

Page 7: Modes And Routing
Pushing the knob once again will turn the loop back on. 3. Modes and Routing MODES: Duophony offers 3 parallel blend modes: XY Mix Loop X and Loop Y are mixed proportionally. For example, if Y is set to 30%, X will be at 70%. - Page 8 Well, without this option, once you’re done hooking up everything on your pedalboard, the effects that you’ve put in Duophony’s effects loop will be permanently stuck in paral- lel configuration, there’ll be no way to have them combined in series, without rewiring your pedalboard.

Tips: Sometime you only need a few presets, you can avoid having to shuffle through all 8 preset banks by restricting the number of bank that can be accessed. This can be configured in the Global Setting (see chapter 7, page 12). 6. - Page 12 Trails Trails enabled: If you have a delay or a reverb pedal in the loops, you can have the delay or reverb tails fade out, instead of abruptly cut, when the Duophony is bypassed. This feature is only meaningful if the loops contain delay or a reverb pedals.

Page 15: Using Modulation
Conceptually it works like this: FX Loop INPUT OUTPUT FX Loop Duophony as a Tremolo pedal Note that, if you disable one of the loops, then you got yourself a standard tremolo effect acting on the active loop signal. FX Loop INPUT... - Page 16 The modulation engine features: 8 LFO shapes - Sine, Triangle, Exponential, Sawtooth, Reverse Sawtooh, Square, Pulse1, Pulse2. 2 modes - Normal (centered) or Panning. 7 subdivisions - Whole, Half, Quarter, Dotted 8th, Eighth, Triplet, and Sixteenth. Hz or Bpm display mode.
- Page 17 Tips: Setting the speed to an exact Hz or BPM. When using the touch slider to set the modulation speed, at times it may be difficult to set the value to an exact number that you have in mind. For instance, you are trying to set the speed to be exactly at 90.5 bpm but can’t seem to hit the exact number.

Page 18: Using Expression
Only one parameter may be mapped at a time. Connecting an expression pedal to Duophony On power up, Duophony will try to detect the presence of any expression pedal connected to the EXP/AUX port, and configure the internal processing accordingly. Therefore, make sure that the expression pedal is already connected to Duophony prior to powering up the pedal. -
Page 19: Using Aux (External) Switches
For detailed information on how to do this, please see chapter 7, page 13. As with the expression pedal, the external switches must be connected to Duophony prior to powering the pedal. - Page 20 MIDI CHANNEL Globals Duophony is pre-programmed to use MIDI channel 1. You can change the channel number to any number from 1 MIDI Ch. Channel 1 through 16 in Global Settings menu. MIDI CLOCK Channel 16 MIDI clock allows you to sync the tempo of the LFO in Du- ophony to other gears via MIDI sync timing pulses.

Page 21: Example Applications
The L and R outputs of Duophony are routed to separate jacks. For the inputs, sends, and returns, the L and R channels share a single jack which accepts TS connection for mono signal, or TRS connection for ste- reo signals. - Page 22 Loop N MIDI (optional) In the example above, a stereo delay and a stereo reverb are placed in Duophony’s FX Loop. You can take advantage of Duophony’s flexible routing (parallel or series) to achieve various delay + reverb combina- tions.
