Erica Synths has released firmware v1.3 for the Perkons HD-01 hybrid drum synthesizer, adding custom samples per bank, a new CHORD algorithm, real-time chromatic quantisation, dotted BBD time divisions, and several workflow fixes. The Perkons HD-01 features four hybrid voices (digital sound engine + analog multimode filter with overdrive), a four-track sequencer with per-step ratchets and probabilities, and built-in BBD emulation and compressor.
Version 1.3 features: each bank can now have its own sample set (placed in the bank folder 00, 01, etc.; default sample set loads from root SAMPLES folder if absent); a new CHORD algorithm accessed via Voice 3, Algo 3, Mode 3 (replacing a Karplus mode) with PARAM1 morphing waveforms and PARAM2 setting the chord; real-time chromatic quantisation of voices enabled by pressing the 13th key of the second row in the config menu; dotted BBD time divisions/multiplications added (new sync ratios: 1/32, 1/16T, 1/16, 1/8T, 1/16D, 1/8, 1/4T, 1/8D, 1/4, 1/2T, 1/4D, 1/2, 1/1T, 1/2D, 1/1, 1/1D); parameter lock for tune now lasts until next trigger (previously required locking each step separately); and a MIDI CC filter enabled via the 9th key on the third track.
Fixes include: manual trigger now works without a started clock; audio mute clicks eliminated; trigger mute on allows triggering voices with SHIFT+TRIG keys. The update requires backing up the SD card, placing the .img firmware file on the root directory, then holding all four voice trigger keys while powering on. Updated manual and config sheet are available for download from the Erica Synths support page.
The Perkons HD-01 BLACK edition (€1,700, VAT not included) launched earlier with a black finish to match the Erica Synths module aesthetic. The v1.3 firmware is a free update for all Perkons HD-01 owners.
