jellyfish

jellyfish free software-synthesizer by de la Mancha

jellyfish is a free software synthesizer developed by de la Mancha. Available format(s): VST for Windows.

jellyfish is a 4-oscillator synth with multiple modulation methods between the oscillators and of their various parameters which guarantees plenty of movement in the sound. This is great for evolving pads, wobbly bass, vibrant leads or just plain strangeness. Using addition, subtraction, phase difference, ring modulation or phase distortion, the oscillators can modulate each other to get a wide variety of sounds. 2 tempo-sync LFOs and an ADSR envelope can all modulate this inter-osc modulation, as well as pitch, filter cut-off and each other. A pair of resonant filters and a tempo-sync delay complete the deal.

Features:

  • 4 oscillators arranged in pairs, with each pair able to modulate each other.
  • 9 inter-osc modulation methods, including phase distortion, phase difference and ring modulation.
  • ADSR envelope per oscillator pair, with unlimited values and definable contours.
  • 2 resonant low pass filters with flexible routing.
  • 2 tempo-sync LFOs with 16 waveforms and adjustable phase.
  • LFOs can modulate the inter-osc modulation, pitch and filter cutoff for each pair.
  • LFO2 can modulate LFO1.
  • 1 ADSR envelope can modulate as per the LFOs and modulate both LFOs.
  • Tempo-sync delay, with damping and mix level.
  • Oscillator and LFO note-on sync.
  • 11 waveforms per oscillator.
  • MIDI learn / MIDI CC parameters defined.
  • 50+ presets by runagate.

Jasuto

Jasuto free software-synthesizer by Jasuto

Jasuto is a free software synthesizer developed by Jasuto. Available format(s): stand alone application for iOS, Android.

Jasuto is a modular synthesizer for iOS and Android. It is flexible in terms of synthesis techniques – you can achieve additive, subtractive, FM/PM/AM and even hard-sync synthesis all pretty easily.

Both the synth and all the parameters are in one object called a scene. A scene is made up of nodes, these are the objects that do the processing and what you directly manipulate to make, modify or otherwise bend the sound. Processing happens top-down. So the top of the scene is generally where you would have your oscillators, the middle is where you would apply your filters and effects, and the bottom is where you would output the sound.

Instead of using the traditional method of drawing wires manually to create the signal path, Jasuto does this a little differently. Basically each node has a controllable radius and range. The radius is used to set the physical size of the node and the range is used to set the receiving range of the inputs. [Read more…].
