JellyFilter

Do you need good lead lines in your production? A synthesizer, biting hard or teasing soft? A synthesizer, flexible to bend to any kind of synth sound? JellyFilter is the solution.

JellyFilter was copied from a red Swedish lead synth idol (which is available in 3 versions to my knowledge) and implies some more functionality, at some point less functionality.

Current download of jellyfilter is available under software.neuenberger.de

Technical details:

Polyphony / Timbrality:

Max 8 voices (additionally it is depending on CPU power and complexity of voice), 1 channel.

Oscillators:

3 Oscillators with Controllable Detune (Unisono) per Osc: Saw, Sine, Square, Pulse with PWM, Noise (Osc 1+2) Pitchbend +/- 12 Halftones

Modes:

Poly, Mono and Legato (Like mono, but does not restart Envelopes if Voice is not released)

Filter:

12dB and 24dB LowPass and Bandpass with resonance, Highpass, envelope amount and cutoff, possibility for self-resonance (protect your ears)

Envelopes:

ADSR for the Amplifier section, ADSR for the Filter section. Both Linear and Exponential available.

Effects:

Portamento, Distortion, FM OSC 2-> OSC 1, FM OSC 3-> OSC 1, Sync Osc 1 to Osc 2, Bit Reduction (Lo-fi effect) Extra Distortion for Osc 3. Chorus with Rate, Depth, Delay and Type (Triangle, Saw, Square).

Modulation:

Attack Decay Envelope: Either to FM amount, to OSC 2 or to OSC 3. Fast and Slow available

LFO Modulation Parameters:

Types: Saw, Triangle, Square, Random

Rate and Amount

Destination: to OSC 1+2, to OSC 2, to Filter, to PW

Optional Sample and Hold (+Synchronize to tempo)

30 July 2008: JellyFilter v3.0.1 available


As mentioned earlier the product was tested and working well on Cubase SE without any issues. Now I was running a test with Cubase Essential 4 to see that there is a major latency problem and I figured out what it is and made a quick fix of it ... there was simply a wrong assignment of a wrong constant latency.
Additionally JellyFilter version 3.0.1 now supports pitchbend commands.

 

28 July 2008: JellyFilter v3.0 available


Since version 2.0 a lot of development effort has been put, there are a lot of more ideas, but here it is. Summarized, we added Oscillator 3, Legato Mode, Lo-Fi "Distortion", either 12 dB or 24 dB Filter Steepness, Sample and Hold for LFO Modulation, Exponential or Linear Envelopes, Fast/Slow Modulation Envelope. Here in detail:
We added an Oscillator 3 that can be used as subbass or additional FM source to Oscillator 1. It also has its own additional Distortion.
A standard Chorus now can fatten the sound even more. The Chorus can be adjusted by Dry/Wet, Rate, Depth, Delay and Type (Triangle, Saw, Square).
For 303-type sounds there is now a new mode called Legato: This will not restart the envelopes until the voice is completely released which can be useful for smooth crossovers between different notes.
For Lo-fi enthusiasts there is a Bit Reduction (BitRed) functionality that can reduce the information down to 2 bits. Old Digital-sounding Video-Console sounds can be created with this easily.
Filters can be set up either to 12 dB or 24 dB steepness which allows the user to produce "warmer" sounds with the 12 dB option.
The LFO Modulation has been accompanied with a Sample Hold (S/H) functionality that can be synchronized to the tempo of the music.
Envelopes for Amp and Filter now can be switched to exponential as well. This results in even smoother envelopes.
Finally the Modulation Envelope ("Mod-Env") can be fast or slow - you choose! If you need a slow sync-sound, you will choose slow, for the booming bass probably fast :)
From the performance point of view we tested the following in our premises: On a 2.0 GHz Intel(R) PC it was no problem to play 9 notes concurrently (Full complexity, i.e. Bandpass filter 24dB, Exponential Envelopes, Chorus enabled, Osc 3 used), on a 1.5 GHz Intel(R) Celeron(TM) 6 at the same time (same complexity). As VST Host we used Cubase SE.
