  • Page 4 What is the deFormer? The deFormer were originally ment to be a unique granular effect processor only, but when the granulator part was finished, only a quarter of it’s DSP power was used, so a synth section and some additional effects was added.
  • Page 6 DeFormer front In: Adjusts the total input level from audio inputs 1 and 2. Out: Adjusts the total audio output level. Mix: Adjusts the mix between the original audio input signal and the signal processed by the granulator effect. Edit: Enters the edit pages menu, for editing sounds, sequences and effects.
  • Page 7 Freeze: Freezes the granulator effect, so the audio held inside of it will play back repeated until freeze are released, by pushing freeze again. Run: Starts and stops the two track sequencer. The 3 knobs right under the display: Referred to as ”Edit knobs” (Two potentiometers and one rotary encoder) Used for various editing function on the edit pages.
  • Page 8 DeFormer back Connections 9VDC: Connect the supplied power adaptor to this socket. The switch beside it are the power on/off switch. MIDI in: Connect this to the MIDI out of a MIDI transmitting device (MIDI keyboard, sequencer, computer or whatever).
  • Page 9 The Preset select page This is the deFormer main page. Every time you turn on your deFormer, it will for a short while write: ”Gotharman’s deFormer”, and right after that, it will go to this screen. On the top of the display it writes the name of the selected preset. It remembers what preset was selected, when it was turned off, and goes to that preset when it is turned on again.

  • Page 10: The Edit Pages

    The Edit pages NOTICE: The edits you do, are not automatically stored in memory. If you would like to keep your creation, you wil have to SAVE the preset. How to do that, are explained later in this section. How to enter the edit pages from the preset select page: Push the ”Edit”...
  • Page 11 When you enter an edit parameter page, use the Dec/Inc buttons to select the various parameters inside the group, and use the the knobs right under the display to edit the parameters. Sometimes the 16 knobs on the lower half of the front are also used for editing. That will be explained in the following sections.
  • Page 12 Explanation of the edit pages The Sequencer pages The deFormer sequencer are a two-track analogue style type with a maximum of 32 steps for each track. Each track has separate subtracks for note, velocity and controller. Tracks are "recorded" by entering values for each step, using the 16 step knobs.
  • Page 13 When on a sequencer edit page, and the sequencer is running, progression on the steps can be viewed on the 16 step LED’s: Push the Edit button to enter this page: Edit 1: Track 1 on/off. Edit 2: Track 2 on/off.
  • Page 14 The 16 step knobs, selects a note value for step 1-16. The last selected note value are showed in the lower right corner of the display. The 16 step knobs, selects a note value for step 17-32. The last selected note value are showed in the lower right corner of the display.
  • Page 15 The 16 step knobs, selects a velocity value for step 17-32. The last selected velocity value are showed in the lower right corner of the display. The 16 step knobs, selects a controller value for step 1-16. The last selected controller value are showed in the upper right corner of the display.
  • Page 16 The 16 step knobs, selects a controller value for step 17-32. The last selected controller value are showed in the upper right corner of the display. Edit knob 3 (the encoder) adjusts what controller number you want to control. This number is shown on the upper left of the display.
  • Page 17 Edit 1 – Track MIDI output channel: Select what MIDI channel you want the track to control. Only active if control = ext. Encoder – Control Int/Ext: Select if you want the sequencer track to control deFormer’s internal synth (Int), or an external MIDI device (Ext), on the selected MIDI channel.
  • Page 18 Edit 2 – Key transpose: If on, received midi note-on’s will transpose the entire sequence in semi- tones in real-time. Encoder – Key trigger: Selectable modes: -Off: The sequencer are in normal mode. When you hit the Run knob, it starts running, and when you hit it again, it stops.
  • Page 19 Sequencer track 2 Has the same set of parameters as track 1. All parameters can be separately adjusted for each track.
  • Page 20 This effect is very useful for creating variations in repeating patterns. The deFormer has 4 note randomizers build in. MIDI channel and note range can be adjusted separately for each note randomizer. If a note randomizer MIDI channel are the same as deFormers global MIDI channel, that randomizer will treat notes sent to the internal synth.
