GyL Synths GyLinx 3 (2)

Inspired by an Eurorack filter modul (G-Storm Gyrinx), which based on the Synton Syrinx, an old, but tricky synthesizer.

Use the fxb/fxp preset saving system of your DAW/Host, the txt-based one on the GUI prone to save some seq note incorrectly!

Created 40 presets in Savihost (optimized to the middle-C note and close to it, but you can transpose them with the OCT V12), some of them enjoyable, some just function test or demo, so feel free to modify them, create your own sounds/rhythms and save to the fxb bank. You can save more banks with different names, if need more patch slots.

(the bad news for Win XP users: I started it in newer FS Alphas, so maybe will not run on your system – but worth a try)

Click on the HELP button in System to read more about the features and handling, I tried to collect useful info in it.

The Syrinx was only an inspiration for me, but created by my ideas.

If you want a more authentic Syrinx inspired VST synths, try the great CyRinx I/II from Kevin Brown – I half-made my one, when recognized that Kevin has already made the 2 CyRinx…

Created a new multi-lane sequencer to it, the oscillators are wavetable based ones (came from my earlier 8&8 + created some analogish-looking tri-saw-square-pulse waves manually to it) and has more oscs than the original, there is a dedicated formant/vowel osc too, the delay has some new features (L-R ratio, cross mod), added my PseUn (pseudo-unison) to the effects, each module has Random-Reset, GUI resize, MIDI learn, Envelope Times knob (inspired by Dreadbox Typhon), DePitch to compensate the default 100% keytracking on the cutoff frequencies, morphable LFO waves,… but the heart of the synth is the filter, I think.

Surely far from the perfect, still has some issues what I plan to repair or improve, but enjoyed it a lot during the patch making and hope, you will too.

GyL Synths Acid Robot 5 (1)

Acid Robot is not a Swiss Army tool, a simple synth, but can produce nice sounds and rhythmic patterns.

It has a key tracking, multi-lane sequencer with step based smoothing, 2 oscillators with PWM on ALL waveforms (tri-saw-pulse), distortion, a multi-mode filter, LFO and envelope modulations on the main parameters, a stereo delay, randomization, MIDI learn, GUI resize,…

If the sequencer is bypassed, the modulation part is different and you can use it as a normal synth. If the seq is on, each step retriggers the decay envelopes and the gate time follows the decay time – adjustable with the D/R knob. Added a simple stereo delay to it. The L-R time ratio is adjustable from 2/3 to 3/2. The max feedback is 1, where it became a short time “looper”. The shortest times with higher feedback can add metallic timbres to the sound.

I created my patches in SaviHost, but there was a small issue with the saving. The best way was: saved the created preset to the fxb and txt banks, then closed and re-opened SaviHost. This way the saving/loading was always successful. If you can live with it, create your own patterns and sounds.

You can read more about the features and tricks if click on the HELP button – tried to add many useful info to it.
