Got it to work with following instructions found here and with bash scripts/modifying examples:
https://github.com/HolyCityAudio/ESP32/tree/master/faust
- downloaded, moved faust-build.sh and made executable as instructed, modified with serial port name.

To add potis:

MCP3008 - 8-Channel 10-Bit ADC
P0915N-FC15BR10K - 10K THT + Panel mount pot

SPI default pin mapping:

SPI | MOSI | MISO | CLK | CS
VSPI | GPIO 23 | GPIO 19 | GPIO 18 | GPIO 5
HSPI | GPIO 13 | GPIO 12 | GPIO 14 | GPIO 15
