   0 reviews  -  304 views

    Description
    Gotharman's duoSpaze is a 4 part duophonic/multi-timbral synthesizer/sampler with analog filters, effects and sequencer.

    Parts:

    duoSpaze has 4 parts, 2 synth parts and 2 sampler parts. Each part ends with a VCA, and inbetween the synths/samplers and the VCA, up to 2 analog filters, 2 digital filters and 4 insert effects can be inserted, via a touch based Audio Matrix. The parts can also be sent to 2 Output Effects.

    Synth Parts:

    Each of the 2 synth parts of duoSpaze has 2 oscillators, Oscillator 1 and Oscillator 2. 4 oscillators in total.

    Oscillator 1

    Generates a waveform that is morphable between sine, triangle, saw, pulse and feedback waves. Pulse width are adjustable for all waveform types. Oscillator 1 outputs both an audio range signal and a low frequency version of this at the same time, so the oscillators functions both as audio range sound and low frequency modulation, at the same time.
    Pitch, PW, wave and FM amount can be modulated.

    Oscillator 2

    Generates a waveform that is switchable between sine, triangle, saw, square, noise, input L and input R. Pulse width are adjustable for triangle, saw and square, but sounds different from oscillator 1, to have a wider sound range. Oscillator 2 can sync to oscillator 1. Pitch and PW can be modulated.

    Oscillator 2 can frequency modulate Oscillator 1 (FM), the analog filters (FXM) and the samplers.
    Portamento is shared with oscillator 1.

    Ring Modulator:

    Each of the 2 synth parts has 1 ring modulator. 2 ring modulators in total.
    The ring modulator get it inputs from oscillator 1 and 2.
    The level of the ring modulated signal can be adjusted in the output mixer of Oscillator 1.

    Sampler Parts:

    Each of the 2 Sampler part of duoSpaze has 4 sample slots, so it is possible to have 8 samplings in total assigned for each preset.

    Plays back any of the 255 storable samplings, and any of the 64 possible chop samplings within a sampling. Pitch, start point and length can be adjusted and modulated. Samples are chromatically tuned, and has a pitch range of 4 octaves above and 5 octaves below the original sample pitch. Loop mode can be set to Off, On, Free or Sustain. In Free mode the sampling is constantly playing back, and is never re-trigged.
    duoSpaze comes loaded with a bunch of original Gotharman drum samplings.

    The samplers can load and playback Little deFormer samples and use the chop points. It is also possible to create chop points in the duoSpaze sample editor, and use these, and to load all samples from a directory as chops within a sampling, via USB. Chops can be detected by level peaks or by single wavecycles. Single wavecycle chops are an easy way to make loops.
    The samplers has a portamento control.

    Analog Filters:

    duoSpaze has 2 sets of analog HPF+LPF filters, 4 analog filters in total. Each of these sets can be inserted on any part in the Audio Matrix.
    The first filter are a 24dB resonant highpass filter. The second one are a 24dB resonant lowpass filter. Cutoff and resonance for each filter can be adjusted. Oscillator 2 can also modulate the cutoff frequency of both filters (FFM - Filter FM). Cutoff, resonance and filter FM amount can be modulated.

    In connection with the filters, a special G-ray (Gotharman-Ray) circuit can be found, that will add grit and noise. G-Ray intensity, mode, and feedback can be adjusted, and feedback can be modulated.

    VCA's:

    Each of the 4 parts of duoSpaze ends with a VCA. It has 4 in total.
    A VCA can output to either audio output L and R or Output Effect 1 and 2. A pan control adjusts the levels of the audio signals sent to each output or effect.

    An ADSR envelope are attached to the VCA. The VCA envelopes can either be in linear, logarithmic or smooth linear/logarithmic modes. A Drone parameter are available, for opening the VCA without the envelope needing to be trigged. VCA pan, attack, release and output level can be modulated.

    ADSR Envelopes:

    Each part of duoSpaze has 1 VCA envelope and 1 modulation envelope. 8 in total.
    With linear/logarithmic charateristics and the modulation envelopes has an additional offset control. Both the VCA envelopes and the modulation envelopes appears as modulation souces.

    Decay Envelopes:

    Each part of duoSpaze has a Decay envelope, that appears as a modulation source.

    LFO's:

    duoSpaze has 4 LFO's. These are global, and can modulate any parts.
    Waveform is morphable from triangle to saw to square to high speed FM waveforms. Rate can be adjusted. Both the rate and the wave parameters can be modulated.

    Random Generators:

    duoSpaze has 4 Random Generators.
    Changes to a new random value every time they are trigged. Trigger sources can be Part 1-4 and LFO 1-4.

    Insert Effects Processors:

    duoSpaze has 4 insert effects processors. Each of these can be inserted on any part via the Audio Matrix.
    All effects has a bypass switch, a mix parameter and Freeze modulation. Many parameters can be modulated.
    Effects can be linked for true stereo effects processing.
    Insert effects present at the moment:
    - Digital filter/EQ - 16 filter types and 2 EQ types. Derived from Fuzion.
    - Chorus - Gotharman's special chorus with an added Deep parameter, that adds space to the chorus.
    - Pitch-Shifter - +/- 1 octave, +/- 2 octaves or +/- 4 octaves. Adustable sense.
    - Stretcher - Tries to time stretch the input signal, while at the same time keeping up with it. Impossible? -Yes, indeed :-)
    - FM - Adds self-FM to the input signal in +/- 1 octave, +/- 2 octaves or +/- 4 octaves ranges.
    - Resonator - Adds space to the sound.
    - Distortions - 4 types: Valve, Sine, Fuzz, Xdis.
    - Pitch Shaper - 1 input version of Gotharman's special Pitch Shaper, that forces an audio signal to play back at a specific pitch, determined by an adjustable frequency.
    - Glitch Shifter 1 and 2 - Imperfect pitch shifters.
    - Wave Shaper - Re-shapes the input signal.
    - FAT - Adds up to 3 layers of the input sound on top of it. The Phaze of the added layers can be adjusted.

    Output Effects:

    duoSpaze has 2 Output Effects Processors. Each of the 4 parts can send their signals to these.
    Output Effects types:

    - Granulator - Cuts the input signal up in grains, that can be re-arranged. The anAmoNo X granulator can sync to the sequencer.
    - Variator. Creates new variations of the input signal. Both pitch and rhythmic variations.
    - Delay - Delay with time and feedback controls, plus Gotharman's Deep, Size, Beam and Xfade controls. Deep adds space to the delay, Size makes the playback range more narrow than the input recording range, and beam beams the delay to previously unknown places. The Xfade control on this delay, creates valleys between the delay taps. The more it is turned up, the more time the valleys takes up.
    - Roto Delay - New Gotharman delay! This is a 2 tap delay, that is constantly crossfading between the 2 taps. When the Xfade control is turned down, the crossfading is rough, the more it is turned up, the more smooth the crossfading gets. Other controls are the same as the first delay.
    - Bright Delay - First delay, but with a brighter sound, created by a resonator.
    - Bright Roto Delay - Roto delay, but with a brighter sound, created by a resonator.
    - Reverb - Synthetic reverb.
    - Filters 2 - Some new digital filters. 6 Types.

    Randomizers:

    duoSpaze has a Synth parameters Randomizer and a Sequencer step values Randomizer. On each of the Randomizers, blocks like oscillators, filters, effects, note track and many others can be switched on or off, so you only randomize the blocks that you want. Percentage of randomization is settable.

    Sample Recorder:

    - Samples are kept in NOR FLASH RAM, that is much more stable than the widely used NAND FLASH, and that does not get any bad blocks.
    - Samples are kept even after a power off.
    - Total recording time: 22 minutes mono/11 minutes stereo.
    - Single sampling max length: 12 minutes mono/6 minutes stereo.
    - Max. 256 samplings/16.384 chop samples.
    - Recording sources: Audio input and output, USB import of .wav files.

    Audio Input:

    It is possible to record samplings from the stereo audio inputs, and they can be routed to the analog filters and the effects processors.

    4x 64-step Note sequencers with MIDI Out:

    Each Note track has 3 subtracks:
    - Note: Note input by touch or by realtime record. Octave and bar selected by knobs. Steps on/off selected by touch.
    - Gate Time: Values inputted by touch. Bar selected by knob. Steps on/off selected by touch.
    - Velocity: Values inputted by touch. Bar selected by knob. Steps on/off selected by touch.

    8x 64-step control sequencers with MIDI Out:

    Each Controller track has 2 subtracks:
    - Control Values: Values inputted by touch. Bar selected by knob. Steps on/off selected by touch.
    - Slide Time: Values inputted by touch. Bar selected by knob. Steps on/off selected by touch.

    Play Modes:
    - Multi-timbral: Complete control of each of the 4 parts. Key range and MIDI channel settable for each voice.
    - Duo: The 2 synth parts plays duophonic. Sample part are still multi-timbral.
    - Stereo Samplings: The 2 sample parts are mixed together, the left channel goes through the filters/effects of part 3 in the Audio Matrix, and the right channel goes through part 4 filters/effects.

    Morphing System:

    - Each preset holds 2 sets of sound parameters. By using the Morph knob, or by assigning modulation to this, when morph mode is "Synth" or "Both", it is possible to morph between the 2 sets of parameters. Activating the "Morph Settings" touch button, will reveal the second set of parameters.
    - The sequencer also has 2 sets of parameters. Turning the Morph knob, when set to "Seq" or "Both" mode, will morph between the 2 sets of parameters -Morph from one tune to another.

    Touch Screen Keyboard:
    - Included!
    - On the Preset Select screen, a large touch keyboard with Y-mod is represented. On the synth edit pages, a small touch keyboard without Y-mod is represented in the bottom of the pages.
