Artium Instruments has launched a Kickstarter project to fund production of The Doppler, a new polyphonic FM desktop synth.

The Doppler is a polyphonic, 2-operator FM synthesizer that offers a unique approach to sculpting, tweakability, and 8-note polyphony. They say it’s “designed for sonic exploration, where every knob twist reveals a new sound that’s uniquely your own.”

Features:

• 2-Operator FM Synth – The developer sayst that ‘Ultra-tweakability ‘is at the core of the Doppler. It features a single, powerful algorithm, but event the subtlest tweaks lead to big shifts in the overall sound.
• Quantized Modulation – The modulator sine wave features two rotary switches that control its frequency through a quantized octave and semitone shift. The Octave rotary switch offers a 5 octave range, allowing you to go two octaves above and two octaves below the carrier’s frequency. The Semitone rotary switch gives you a 12-semitone range, from the base note up to 11 semitones above. Both switches click into place and are perfectly quantized in relation to the carrier’s frequency.
• Advanced Envelope – The Doppler features a standard ADSR envelope, but there are a couple of nuances that enhance its functionality. By default, the ADSR envelope only affects the carrier wave. However, when you flip the Env Mod toggle on, the envelope also influences the amount of frequency modulation applied to the carrier. On top of that, the Mod Trail knob lengthens the attack value, but only on the modulator wave. This gives you the ability to make the modulation swell in, adding an extra layer of depth.
• MIDI Control – The Doppler is controlled via MIDI through a USB-C port, making it easy to integrate into many setups. Most modern, class-compliant MIDI controllers with USB functionality will plug in and work instantly with no setup required. Plus, the Doppler powers your controller, simplifying your cord management. For older controllers with only DIN connections, a USB-to-DIN converter works.
• Effects – All onboard effects can be used with external equipment. Plug an external audio source into the rear input jacks, and The Doppler will seamlessly mix the external audio with its synth core, allowing for simultaneous processing of both signals.
  • The Doppler delay is a tap-tempo digital delay with ‘a subtle touch of warmth’. The delay length syncs with an internal clock, which you can set by tapping the red piezoelectric touchpad.
  • The reverb in the Doppler is crafted “to enhance the natural body and ambiance of the synth without overwhelming it”. This stereo reverb lets you move seamlessly from subtle room or hall effects to expansive, cathedral-like soundscapes.

Pricing and Availability:

The Doppler is available to project backers starting at $349 USD. The project has already met its funding goal.
