SOUND LAB NOTES
analog synthesizer
On sale at eBay Sept. 17-22th 2008

This is Soundlab Notes analog synthesizer by Health Club Music. Our style has been compact, brief, and this one follows that.
It has yet another unique feature: the Envelope Follower. And it has two Envelope Generators.

It has the following features:

2 VCOs (Both have Saw Waveforms, VCO2 also has Square Wave with adjustable Pulse Width)
1 LFO with switchable Square, Saw, Triangle, and Ramp Waves
1 VCF that is Resonant and is switchable between BandPass and LowPass Modes
1 VCA
2 Attack Release Envelopes (AR1 or the LFO can be switched to retrigger both Envelopes, looping them like LFOs)
1 Manual Trigger Arcade Button can trigger or gate the AR Envelopes
1 Envelope Follower that is triggered by the External Audio Input and can be sent to VCO 1, VCO2, VCF, and VCA
Many input and output jacks, look at the photos!

 

 

The VCOs can be Synced with the Sync Switch and can be Linked by the Link Switch. When the Link Switch is on, the VCO1 Freq knob tunes both VCOs and the VCO2 freq knob offsets VCO2 from VCO1, so you can play the same chord at different notes. When the Link Switch is off, both VCOs are tuned independently of each other.
There is a headphone amp on the main output so you can listen to Notes on your headphones. There is also one pre-amp on the audio input..Hook up your guitar with or without your effects pedal and you will be happy. You can also play an external CV input on both oscillators! The CV input jacks are linked, or you can disconnect them by plugging in your external CV on just the CV 2 input.

These are some mp3 demos of Notes.

The circuit on this synth is based on a design by Ray Wilson. Check out www.musicfromouterspace.com for more of his exciting analog projects and PC boards.
