Notes
# Breathing waveshaper
NTO triangle audio passes through one actual TWS channel while a slow GTS changes its transfer curve.
## Start here
Lower the monitoring level before patching. These are documented patch designs, not claims of hardware audition.
Unless this recipe uses the right Mix Pro for control voltage: center its DC offset, zero unused channels, and bring up only the cabled audio inputs. Connect Audio Interface MIX OUT to your normal monitoring chain.
1. Tune NTO to a comfortable low-mid drone. Start TWS channel 1 input level low and +1 fully down.
2. Set GTS upper to a 4–8 second cycle. Start TWS CV 1 depth at zero and increase until the timbre moves.
## Cables
1. GTS XL upper END OUT → GTS XL upper TRIG IN.
2. NTO TRIANGLE → TWS IN 1.
3. GTS XL upper OUT → TWS channel 1 CV 1.
4. TWS OUT 1 → Edelweiss right Mix Pro IN 1.
5. Edelweiss right Mix Pro OUT → Audio Interface AUX IN.
## Listen for
A steady pitch with periodic shifts in harmonic emphasis; the waveshaper is not a pitch sequencer.
## Play it
Raise +1 for a second shaping stage, then reduce CV depth to keep a recognisable center.
## If it misbehaves
No change: check that the cable enters IN 1, not New Ring SIGNAL IN on the far right.
