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

Filter:

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

	21 December 2015: JellyFilter 3.8 released
	Well, sorry for the long time since my last version, I was quite busy on other issues but finally could dedicate some time for the development of JellyFilter, I even updated the user manual ... The features that I introduced are: More variations of oscillators that allows to choose shape variations for Osc 1 and Osc 2. Appregiator Musical functions: LFO 1 has the possibility to hold musical levels, such that it can play certain notes repeatedly, e.g. Octave+Fifth, Major Notes, Octaves, all notes. Combined with noise this can play random tunes as well! Additionally the polarization of LFO can be negated. Additionally there is attenuation and release for LFO so that the amount can be changed along the time a sound is played. Architecture: There is the possibility to vary the architecture, i.e. the audio flow of a sound, so that e.g. fx is before filter or after filter etc. AHDSR Envelope for the Amplifier section Both Envelopes of Filter and Amplifier section get a "repeat count": This functionality allows to create sounds like handclaps or repeating sweeps. The Envelope is looped in the phase of A-H-D until the repeat count has been reached, then the Sustain Phase is initialized. This means a boost in sound creational possibilities for JellyFilter. More knobs in kind of "submenus", so if you press the "Special" button which is placed in certain sections (Like LFO, Osc 1+2, Delay) Knobs below and above the "display" get a contextual meaning and you can turn these knobs to change the sound. This is a user interface change, it means that there will be a number of "invisible knobs" and it allows to place a lot more functionality on the small "panel" that is available on a users screen, buttons that are used often will of course remain on the panel, but others which are known to be used only rarely are put in submenus. Envelopes can be either Linear or Exponential. This can be switched in the Voice special menu. Mixing of Oscillator 1 and 2 can be done using either adding (up to now the only possibility), Amp modulation or distort the other oscillator. That means 5 Options in total. Talking about facebook there is a community which I launched to give JellyFilter users the chance to get connected with each others and to exchange sounds etc. and to also post. That would be great! You can reach the new JellyFilter Facebook community by following this link. So talk to you on facebook. I will answer questions there.
	01 November 2011: JellyFilter 3.8 planned and Facebook Community launched
	There was a lot of time that passed by since my last updates, I am currently very involved in other work, for there are bills to pay ... Since there is a version sleeping on my development PC with lots of improvements I hope to bring it out at the beginning of next year. I will call it JellyFilter v3.8. Planned major features are: More variations of oscillators that allows to choose shape variations for Osc 1 and Osc 2. Delay Appregiator Musical functions: LFO 1 will get the possibility to hold musical levels, such that it can play certain notes repeatedly, e.g. Octave+Fifth, Major Notes, Octaves, all notes.

Demand for a Mac version of JellyFilter will be met in spring 2012. I will keep you updated.

	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.
