B. Serrano has released HADES, a substractive synthesizer, powerfull and low in CPU usage.
It has some nice features, like the “Steps level” in each LFO, which lets you create rhythmic motifs. The LFOs can run freely or BPM sync. Each oscillator has a waveshape level for sound color. HADES is 6 voices polyphonic.
Also, PULSAR 4 (polyphonic synthesizer) has been updated to version 1.4 and OSIRIS (.wav player with all classic modules of substractive synthesis) has been updated to version 1.2. Both updates reduce CPU usage considerably.
