Just a suggestion to you both - wire in two RP235xs linked by PIO I2S or TDM and an SPI bus. No matter how much you optimise the code, eventually you'll need more processing power to implement more features. Oscillators and envelopes in the first MCU and filters and effects in the second.
And this MCU only costs about the same as a few op-amps![:-)]( "Smile")
Good luck !
