"Granular workstation with sampler, synth, effects processor and sequencer

Gotharman's Little deFormer combines a granular effects processor with special effects like TimeStretcher, StepGranulator and PitchShaper and more usual effects like Reverb, delay, distortion, compressor, filters and bit manipulation, with some special parameters, with a 100 minutes sampler, a synth and a step sequencer. A MIDI Note Randomizer is also included.

Both the samplings and external gear, connected to it's 2 audio input can be effected. A complete list of effects can be found in the specs section below. Watch and hear Little deFormer in action, in the video's section. I have planned to use the Little deFormer as a platform for engineering new effects, so additional effects will be added now and then, which will be available as free downloads on this site. These updates will be available as MIDI sysex files in".syx" format, and you will need a program like MidiOx to download these to Little deFormer.

The 4note polyphonic sampler makes it possible to record your own samplings directly from the 2 audio inputs, or resample it's audio output. Samplings are stored in FLASH RAM for instant recall, without any loading times. Up to 100 minutes/999 samplings can be kept. Start and end points can be changed in realtime and modulated, and it also has functions like AutoChop, for a conveniant and easy way to cut up long samplings. Each sampling has it's own Phaze effect and filter with LPF, LFP2, BPF, BPF8, HPF, ADD, BEF, BASS, LOFI and SHAPER modes, and a filter mix parameter. It is also possible to adjust the filter response, to create filter types, that have never been heard before. The Little deFormer comes loaded with samplings of other Gotharman gear. Instead of samplings, it is also possible to use Little deFormers buildin oscillators for sound generation. They can morph from sinewave to triangle to sawtooth to squarewave to noise. Pulsewidth modulation is possible on all waveforms.

The Little deFormer comes with an expansion port. Right now, only an analogue expansion box, that adds CV inputs and trigger inputs/outputs are available, but it is my plan, to add more expansions later.

Make sure to check out the AnaX Analog Expander for Little deFormer too

Sampling section

Will come loaded with samplings of other Gotharman machines See list below!
Nonvolatile internal storage of 100 minutes of samplings / max 999.
Maximum possible sample time for one sampling is 100 minutes.
When samplings are recorded, they can be selected just like waveforms on a synth NO loading times!
16 samplings can be assigned to the step buttons for each preset (512 presets)
Buildin Oscillators can be selected per step button instead of a sampling. These can morph from sine to triangle to saw to square to noise, and all waves can be pulsewidth modulated. *New in MkII
4 note polyphonic
Each sampling has its own filter All of the filter types from deMOON plus some new odd ones, with added filter shape adjustment and positive/negative mix
Each sampling/Oscillator has an envelope that can modulate pitch, filter cutoff, filtermix and sample output level.
Samples start and end points can be adjusted in realtime and modulated
Nondestructive AutoChop After autochop is performed, it is possible to adjust, add or delete choppoints
Resampling with effects
Quick Record mode lets you instantly record a sampling, whenever you want, just by pressing the "Exit" and "Freeze" buttons at the same time.
Sample Record Auto Trigger. Starts sample recording automaticly, when the audio source reaches an adjustable level. *New in MkII
Effects section

Both sample/oscillator voices and external audio sources connected the audio inputs can be processed through the effects.
Sample/oscillator voices and audio inputs can be assigned to one of four effect busses. Each effect are assigned to a bus.
Audio can be saved together with an effect preset, for easy recall of THAT perfect moment!
Gotharman's granulator with zeropoint detection and 2 granulating tracks.
Gotharman's Variator effect: A granular effect that will create variations of the audio input.
Gotharman's Abstruct0: effect. A triple random granular effect.
TimeStretch: Grainy realtime timestretching of any input signal.
Delays with some new odd parameters like "delay box depth" and "beam" and "Freeze".
When a delay is frozen, it's audio contents can be saved as a sampling.
Reverb: Not a clean convolution one, but a FAT synthesized reverb with many sound possibilities
Bit manipulation effects like "bit reduction" (of course) and a newly designed Gotharman effect "Obscembler" a bit weird.
Various distortion effects
Glitch Shifter It is definately not a pitchshifter, so it MUST be a.....
Gotharman's PitchShaper From my eurorack module with the same name, with some new added parameters, plus a new oneinput variation.
Gotharman's MIDI triggered compressor
Filterbank with some newly engineered filter types, filter shape adjustment and both positive and negative mix
Effect functions: Copy effect, randomize effect *New in MkII
Sequencer section

32 track, 32 step TRstyle step sequencer
512 patterns (one for each preset)
512 Songs *New in MkII
4 controller tracks Assignable to most parameters
Able to control both the internal samplings, synthesizers and effects as well as external MIDI gear
Control tracks can be linked directly to note step tracks, for melodic playback
Each track, both note and controller, can have separate length settings *New in MkII
Each controller track has separate time signature settings *New in MkII
2 presets (patterns) can be linked together, with adjustment of how many times each preset should play *New in MkII
In Song mode it is possible to arrange the playback of patterns in 120 steps. For each step it is possible to adjust, how many times track 1 should play back *New in MkII
Syncs to MIDI clock, or any other clock source through the AnaX Analog Expander
Sequencer functions: Clear sequence, Copy sequence, Randomize sequence *New in MkII
Note Randomizer: 4 channel randomizer attached to the step sequencer
Each channel has: Noteon probability, velocity and time parameters.
Modulation

10 LFO's with morphing between waveforms: Triangle, saw, square, pulse, unlinear highfrequency waves and random. LFO's rate, wave and mod amount can be modulated.
The LFO's can also be keysynced, and they can loop or only run one time. *New in MkII
16 voice trigged random modulators One for each sampling/oscillator. *New in MkII
4 Sequencer tracks.
8 knobs.
MIDI CC's
Velocity. *New in MkII
Modulation matrix with 32 sources and destinations at a time. Allmost all parameters can be a destination.
Presets

512: All user rewritable. Stored in FLASH RAM, so like all other Gotharman products, no battery backup is needed.
When an effect preset is saved, and "Freeze" is on, audio is saved together with the preset.
Transmits and receives preset data via MIDI *New in MkII
MIDI

OS can be updated via MIDI. I have planned to use the Little deFormer as my platform for engineering new effects. These will be available as updates.
Receive and transmits note on/off messages for triggering of samplings and grains.
Most parameters can be assigned to MIDI CC's and velocity. *New in MkII
Receives, tranmits and retransmit MIDI clock."
