Massive Percussa SSP Software Update



via Percussa:

Massive SSP software update! [New recorder; Phase distortion; FX parameters; Live granular; LFO/WTO/ENV updates; Macro module; Preset collection; Bugfixes; Walkthrough video]

Hi everyone,

Time for the next update! This is a BIG one and covers all the work we’ve done leading up to and during the mSSP campaign as well as all the work we did since the campaign ended.

Please visit our forum for the download links and more details

Completely rewritten multichannel recorder / sampler

This was a lot of very hard work and took about 2 months, changes include the following -

1) the recording time limitation has been removed, so you can now record much bigger WAV files. We’re still limited by FAT32 partition file size on the SD card which is 2GB. The input recorder can record up to 16 channels simultaneously while the output recorder up to 8 channels simultaneously. All recording can be done at 48kHz, 96kHz and 192kHz at 32 bit.

You can choose how many channels to record using the ARM buttons for the input and output recorder. Every channel has a PLAY and MONITOR toggle button per output channel so you have full control over how you monitor incoming signals and audition your recordings/samples.

2) all editing is non destructive on large files, which means changes are applied when you save the loaded sample using the Save and SaveN buttons. It also means the operations are instant, with the exception of the normalization button which needs to read file sample levels the first time you use this operation.

This also means the Undo function has been removed and the Normalize/Reverse/Crop functions are toggle buttons now which can be turned on and off.

3) no longer necessary to load WAV files into memory in the recorder, all operations are done directly on the files

4) you can now no longer start a recording if you didn’t arm any channels

5) ability to Normalize/Reverse/Crop large files

6) new waveform visualisation code and new Zoom code

7) new waveform nagivation code using Start/Length

8) new cropping code

9) new normalization code with progress bar

10) new reversing code

11) new Save/SaveN code with progress bar

12) added code to auto-resize GUI components

Bugfixes and Improvements

1) Pitch signal getting stuck on pitch input when switching patches and re-inserting a module

2) better Sample Rate / CPU bars

3) changed voice allocation code so it doesn’t steal voices

4) changed max oscillator frequency to 20kHz



Granular module updates

1) ability to load your own windows from WAV files

2) ability to save standard windows as a WAV file for editing/creating your own windows

3) added extra modulation inputs for new settings/features including window selection and manual trigger input

4) added code to support live input recording and looping with overdubbing, dry/wet mix, overdubbing amount, and toggles to start/stop recording and enable/disable live input.

5) added 8 grain windows with manual selection and modulation target with morphing. Windows include Rectangular, Triangular, Hann, Hamming, Blackman, Blackman-Harris, FlatTop and Sine.

6) auto-resizing code for GUI components

7) added code to draw granular window while being modulated

8) new pan randomization parameter/code while supporting manual pan setting as well

9) new code to support both mono and stereo input depending on how many signals are patched. Also support for stereo output of course.

10) speed up granular drawing code

Current list of granular modulation inputs:

Pitch - pitch of grains

Start - start of grain selection window

Len - length of grain selection window

Freq - freq modulation input

Amp - amplitude modulation input f

In1 - live signal left input

RGate - gate input for start/stop recording

GrF - grain trigger frequency

GrDur - grain duration

NrGr - max number of grains allowed

Rand - randomization of grain duration/pitch

Dub - overdubbing factor for live input

Blend - dry/wet mix between live input and granular output

Pan - panning control for grains

In2 - live signal right input

PanRand - randomization of pan position of grains

Text - input for modulating grain window selection

Trig - manual trigger input for grains

Current list of granular parameters:

Select - file selection

Start - start of selection window for grain selection

Length - length of selection window

Level - level of grains

GrCoarse - grain trigger coarse freq

GrFine - grain trigger fine freq

GrainDur - duration of grains in ms

NrGrains - number of grains allowed

Tune - tuning of grains

Coarse - manual coarse pitch (frequency) setting of grains

Fine - manual fine pitch (frequency) setting

Random - amount of randomization of grain duration and pitch

Dub - overdubbing factor for live input, determines mix of previous signal in buffer with new signal

Blend - dry/wet mix between live input and granular output

Pan - manual pan setting for grains

PanRand - randomization factor for panning of grains

Text - grain window selection

Reverb module updates

1) added extra modulation inputs

2) added algorithm parameters

3) simplified dry/wet mix parameter

Delay module updates

1) added extra modulation inputs

2) added algorithm parameters

3) simplified dry/wet mix parameter

WTO module updates

1) oscillator stacking pitch spread input

2) sync input

ENV (ADSR) module updates

1) added new modulation inputs for ADSR, sustain level and A/DR curve parameters

2) added group toggle buttons (Gr1-Gr4) to group ENV modules into groups such that they change ADSR parameters when one of the ENV’s ADSR parameters is changed.

LFO module updates

1) phase distortion input

2) sync input

3) index and tuning parameters to help with FM patches

4) added inverted outputs for all waveforms, so we now have +/-Sine, +/-Square, +/-Saw and +/-Triangle.

5) added group toggle buttons (Gr1-Gr4) to group LFO modules into groups such that you can change ratio and detune on multiple oscillators simultaneously by changing the ratio/detune parameters on one of the oscillators

New Macro Module

This new module connects to the M1-M8 parameters on the second page at the global menu, and allows you to control multiple modules in the patcher grid using one set of global parameters, so you can create patches where you can control multiple module parameters with a single knob.

New preset collection + samples

We took some time to collect and organize our presets, some of which we created during the mSSP campaign.

Visit the forum for the download link of the presets here

The presets include a wide variety of patches:

1) polyphonic wavetable synthesis

2) polyphonic granular synthesis

3) polyphonic multitimbral FM and sampling

4) sequencing and multi-voice microtonal quantization

5) additive synthesis

6) polyphonic classic subtractive 12-voice synthesis

7) a wide variety of simple patches covering the granular, sampler, … modules

Important notice about the above samples:

The samples in the above download link contain some from the freesound archive. We made sure to only use public domain samples, but please make sure to look up their license before you use them in any recordings, if you choose to use them.

The samples which do not start with a number are produced by ourselves, so you automatically get a license from us to use them, if you have bought an SSP.

New one-hour walkthrough video [posted here]
