# P5

- Scopes realigned with designated areas

# Oscilloscopes
- Each oscilloscope now connected to a gain node to reduce size
- Doubled the resolution of each oscilloscope
- Oscillator volumes offset these gains to decrease natural scaling
- Master oscilloscope added to FX scope
- Attempted to add LFO oscilloscope (and failed)
