faster int32_t substract_32_then_divide
absolute worst case 2 : new variant 2 cycles faster
best case i've found: 30 cycles faster
all my tests showed identical results to the existing function

Bugfix for passthrough
did not work because of missing return - for num_channels<=1, "left channel" was still running..
(1 means pass trough)

Optimize CPU Usage
In my testsketch with 2 x Chorus with n_chrous=4 & #define CHORUS_DELAY_LENGTH (24*AUDIO_BLOCK_SAMPLES),
Cpu-usage decreases from 13.8% to 9.8%

Access Q-bitn from c
You mentioned in synth_dc.h "// if only C language provided a way to test Q status bit...."
Here it is :) . That return (out & 0x8000000)>>27; translates to only one more instruction : ubfx r0, r0, #27, #1 , i decided to use the c -variant because it is better to readable.
I added a function to clear that bit ( clr_q_psr() ), too. Unfortunately, three instructions are needed (read-modify-write)

Bug fix so that downward tone sweeps will work.
Fixed problem with tone_hi - tone_lo computation being done
with unsigned arithmetic, and thus always giving a positive result.
