Oberheim OBXa RAW, no FX

Published on Feb 1, 2020 synthlegends

"Some of my presets and tweaking of the OBXa. I recorded it directly in stereo into my audio interface without any FX in the signal chain. So you can hear some stereo panning of the panned voices. Also in the DAW I didn't use any mastering, Plug Ins or equalizers.

The OBXa was introduced 1980, its forerunner was the OBX. Where the OBX had discrete VCO and SEM 12 dB filter design, the OBXa had Curtis chips.

The OBXa is quite limited in sound design, because it has no mixer for the waveforms and oscillators. There is only SAW and Pulse with PMW, but it has two filter types 12 dB and 24 dB. The only LFO can modulate PMW for OSC 1 and 2, VCO 1 and 2 and Filter. It has got also a random mode (SH). You can sync OSC 1 to OSC 2, which makes nice lead sounds. There is also an unison mode and portamento.

A great feature of that time was the split and layer mode. A famous split sound is used in 1984 from Van Halen.

The OBXa has not very quick envelopes, but is a fantastic synth for fat strings and pad sounds. PMW modulation by LFO independently for the Oscillators is a dream.

In this video I tried to demonstrate these capabilities for long evolving sounds with sweeping filters and evolving PMW as well.

Thanks for watching."

MFOS SoundLab Mini-synth MKII

Published on Feb 1, 2020 Todd Murray

"Here is an MFOS mini-synth MKII demonstration video. The audio is recorded directly to the mixer as raw audio, with no effects or processing. The video is intended to give anyone who is considering building one of these, a sample of the sound pallet. This synth is 100% analog across all audio and control portions of the design. This particular build repurposes an old knife box as a housing. The unit is powered by a 13.5VAC wall wart for the +/-12VDC power supply the synth runs on.

This synth design allows a lot of different modulation sources an destinations for an old school mono synth. I personal believe this is one of the better designs for synths in the small, analog mono-synth category, and provides tons of fun and a useable pallet for adding to any composition.
