Weston Introduces PRO2021 mkII, A Sequential Pro-One Clone You Can Build Yourself


At Knobcon 2025, held Sept 5-7 in the Chicagoland area, Weston Precision Audio introduced the PRO2021 mkII, described as “the best Pro-One clone you’ll ever play.”

The PRO2021 mkII clones the original Sequential Pro-One, but with much better build quality. Where the original had a plastic panel, cheap pots and a problematic keyboard, the PRO2021 mkII features heavy-duty build quality, a metal panel, upgraded pots and switches and a modern keyboard.

Features:

  • Updated clone of the Sequential Pro-One features
  • Music Technologies Group Turbo CPU offers enhanced capabilities
  • DIY project designed to be easier to build, with no hand wiring
  • Fatar keyboard with aftertouch, with controls for filter and pitch modulation
  • Improved PC layouts for lower noise
  • Improved metal-shaft pots and high-quality switches

Details on pricing and availability are still to come. They plan to make it available as a kit through synthCube.

VAEMI Analog Sequencer Features 8-Stages In A Compact Format


VAEMI has introduced the VAEMI Analog Sequencer, an inexpensive 8-stage standalone analog step sequencer.


Features:

  • The sequencer operates with a 12V–15V power adapter and features 8V CV and 5V Gate outputs. It is fully compatible with all modular and standalone systems.
  • Each step includes an individual CV knob and a Gate On/Off switch. These switches allow you to manually select which steps will send gate signals. CV and Gate outputs are grouped on the top panel as “CV Out” and “Gate Out.”
  • Two distinct gate outputs are provided: Short Gate Out & Long Gate Out.
  • Step numbers are printed above each knob and are indicated by green LEDs that light up in sequence. Additionally, a blue LED shows the status of the Long Gate signal.
  • The device includes a built-in oscillator that determines the tempo of the sequence. The tempo can be adjusted via the front panel knob. For external synchronization, a Clock Input is available. When a clock signal is connected, the internal oscillator is automatically bypassed and the sequencer follows the external clock.
  • A red Reset button and a Reset Input jack are provided. Reset In operates with a minimum 5V gate signal. When a signal is received, the sequencer resets to step 1 and remains there for the duration of the gate signal. This allows multiple sequencers to be synchronized or enables creative pattern variations.
  • A green Hold button and a Hold In input are included. When active, the sequencer stays on the current step.

The VAEMI Analog Sequencer is available to order with a full kit price of $120 (normally $150) and an assembled price of $176 (normally $220).

 

Brooklyn Synth & Pedal Expo Returns October 18-19, 2025

 

 

Organizer Paolo De Gregorio let us know that this year’s Brooklyn Synth & Pedal Expo is scheduled for October 18-19, 2025.

The event will be held in a 6,000-square-foot warehouse at 100 Sutton in Greenpoint. Like previous expos, the event offers attendees to try the latest synthesizers, effects pedals, and modular gear with headphones, in a noise-friendly environment.

The show is expected to draw over 1,500 musicians, producers, and gear enthusiasts.

De Gregorio says that the headphone format creates a space where you can hear the nuances of a boutique pedal or get lost in a massive modular patch, without the noise of a typical convention.
