"#JX2044 Quick test of response to PAT MIDI messages (routed to filter cutoff)."

You might remember adamstan84 from previous posts on the site dating back to 2015.

"#JX2044 is my latest synthesizer project. It's an analog synthesizer inspired by Roland JX8P. The "2044" refers to the filter chip I used - V2044 from CoolAudio, which is a clone of legendary SSM2044.

Here are some basic specs:
8 voices, bi-timbral
2 DCO oscillators with CrossMod (AM) block based on JX8P, but with PWM capability, and with added triangle waveform instead of noise for DCO B.
3 ADSR envelopes per voice - with switchable Exponential/Linear shape
3 LFOs per voice - LFOs can be slaved together for typical monophonic behavior. Seven waveforms - triangle, sine, square, rising ramp, falling ramp, random and noise.
4 pole (24dB/oct) resonant low pass filter (with self-oscillation)
DCO B can be used as source for Filter FM
master HPF per layer, adjustable in 16 steps.
Digital effects section per layer, with 4 blocks:
Resonant filter bank with two modes - "VP330 Human Voice" ("Male" and "Female" presets) and Polymoog Resonator with three adjustable bands.
Stereo chorus with three modes - "JX Slow", "JX Fast" and "StringMachine" - the last one using three delay lines modulated with dual LFOs.
4-stage phaser
Delay/Reverb

I tried to somehow group the sounds, but there are some oddballs here and there in between. Anyway, here are some bookmarks

13:09 Patches showcasing filter bank from FX section (choirs and brass)
14:12 Odds & ends 1 ;)
15:07 Synth basses
16:08 Noise sweep
16:32 Mostly pads - including some "pseudo-digital" ones, for example...
