Pretty straightforward except for mechanical assembly, and one with an eye towards doing it all in one module with lots of analog drum voices; based heavily on Moritz Klein's work, but with buffering between (some) stages. Needs a _big_ knob, these are actually 2p6t, which means only six different step counts are available until the replacement arrives - Wiring SW15 (once/stop) and cascade out is easier done via skywiring; only one tl074 and support Kassutronic's KS-20 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on https://www.analog.com/media/en/technical-documentation/data-sheets/8063fa.pdf Altera BGA-36 V36 VBGA BGA-48 - pitch 0.8 mm Highspeed card edge connector for 2.4mm PCB's with 50 contacts (not polarized Highspeed card edge connector for PCB's with 60 contacts (polarized Highspeed card edge connector for 2.4mm PCB's with 70 contacts (not polarized Highspeed card edge connector for 1.6mm PCB's with 50 contacts (polarized Highspeed card edge connector for 1.6mm PCB's with 20 contacts (not polarized Highspeed card edge connector for 1.6mm PCB's with 60 contacts (not polarized Highspeed card edge connector for PCB's with 20 contacts (not polarized Highspeed card edge connector for 2.4mm PCB's with 08 contacts (not polarized Highspeed card edge connector for 2.4mm PCB's with 70 contacts (polarized Highspeed card edge card connector socket for 1.57mm PCBs, vertical, alignment pins, weld tabs, board locks (source: https://suddendocs.samtec.com/prints/hsec8-1xxx-xx-xx-dv-x-xx-footprint.pdf 0.8 mm Highspeed card edge connector for 2.4mm PCB's with 70 contacts (not polarized Highspeed card edge connector for 1.6mm PCB's with 30 contacts (polarized Highspeed card edge connector for PCB's with 08 contacts (not polarized Highspeed card edge connector for 2.4mm PCB's with 20 contacts (not polarized Highspeed card edge connector for 1.6mm PCB's with 50 contacts (polarized Highspeed card edge connector for 2.4mm PCB's with 40 contacts (not polarized Highspeed card edge connector for 2.4mm PCB's with 70 contacts (not polarized Highspeed card edge connector for 1.6mm PCB's with 20 contacts (not polarized Highspeed card edge connector for PCB's with 20 contacts (polarized conn samtec card-edge high-speed Highspeed card edge connector for IQRF TR-x2D(C)(T) modules, http://iqrf.org/weben/downloads.php?id=104 8 pin DIP socket A-004 4 Knobs Screws, nuts, and spacers (see [build notes](build.md)) | | | | | | 2 create mode 100644 Hardware/PCB/precadsr/ao_tht.pretty/SOT-23_Handsoldering.kicad_mod create mode 100644 Hardware/PCB/precadsr/Kosmo_panel.pretty/fastestenv_LED_Hole.kicad_mod delete mode 100644 Hardware/PCB/precadsr/ao_tht.pretty/DIP-14_W7.62mm_Socket_LongPads.kicad_mod create mode 100644 Envelope/Envelope.kicad_pro create mode 100755.
