Improving Intonation using the AJH Synth V-Scale

Improving Intonation using the AJH Synth V-Scale

One of the potential challenges of using a modular synth is keeping multiple VCOs in tune with each other as well as external instruments as you play up and down a scale. Most VCOs have trim controls to improve their tracking, but they can occasionally be frustrating to use: They may require you to remove the module from the case to access them, or the manufacturer might have not have used high-precision multi-turn potentiometers for the trimming controls. Therefore, I’ve added several AJH Synth V-Scale Variable Precision Buffers to my modular cases, and have been happier for it. What sets it apart is that 4 of its 5 outputs have high-precision trimmers accessible from the front panel, allowing you to improve the tracking of connected modules like VCOs and resonating filters.

Intellijel Dixie II+ Sync & Flip: LMS Eurorack Expansion

Intellijel Dixie II+ Sync & Flip: LMS Eurorack Expansion

A nice option for an analog VCO to add to your system is the Intellijel Dixie II+: it’s small, has excellent tracking, supports linear and exponential FM as well as PWM and hard sync, and has six different waveforms. In this movie, I demonstrate creating a hard sync patch with the Dixie II+. For those who wonder exactly what’s going on when you use sync, I focus heavily on what’s happening with the waveform output. I also look at the Dixie II+’s unique Flip function.

Verbos Scan & Pan: Waveform Scanning

Verbos Scan & Pan: Waveform Scanning

There are a lot of voltage-controlled stereo mixers; perhaps lost in the shuffle is the Verbos Scan & Pan. It features four input channels with both voltage and manual control of level and panning per channel, as well as manual control of a huge amount of input gain. In this video, I demonstrate using the Scan portion of this mixer to combine the different waveforms available from an Intellijel Dixie II+, including its sub-octave output plus its sine wave that is saturated by the Verbos. I particularly have fun using an envelope to articulate that mix per note.
