PROS
- • Excellent value for the sheer number of waveforms offered.
- • The hard sync implementation is surprisingly versatile and musical.
- • PWM with CV provides expressive and dynamic tonal shaping.
- • Solid build quality for the price point; feels robust in a modular rack.
CONS
- • The tuning stability isn't quite as rock-solid as higher-end oscillators.
- • Aux output level can be a bit low, requiring gain staging adjustments.
- • Limited modulation destinations compared to more complex oscillator modules.

Frequently Asked Questions
It's not quite as precise as those industry benchmarks, but it's acceptable for most applications, especially when using a stable voltage source.
Absolutely, but be mindful of the tuning drift over longer periods and consider a voltage correction module if extreme precision is needed.
The PWM range is sufficient for most applications, but it's not as extreme as some higher-end modules, which might limit some experimental sound design possibilities.
