Sometimes you cannot find a PC board with just the right circuit.  This was one of those times.  I work with a lot of stereo sources, such as the Ciat-Lonbarde … Read More

Quantity 1 From Control: The e560 is a triple-mode effects module: thru-zero frequency shifter, phaser and ring mod. What sets the e560 apart from other DSP effect modules is the … Read More

Quantity: 1 The Synthesis Technology e580 resampling mini-delay emulates the classic sounds of digital, bbd and tape-based delays with four parameters under voltage control. The E580 recreates the pitch-shift modulating … Read More

I was late to make DIY builds of the Synthesis Technology e560 and e580 modules.  A post on the Synthtech email list alerted me to Dave Brown’s builds. E560 Deflector … Read More

This is the Rollz-5+ PC Board by Meng Qi.  The circuits follow fairly closely the original paper circuits, designed by Peter Blasser.  I am building it with modifications of my … Read More

Finally!  Quantisise with Blue Panel and Furman PL-8C power conditioner all together in the 8U EWI Tour Case.  I upgraded the power strip from the Furman M-8Dx to get better … Read More

Boards are all assembled for the Blue Panel.  Left to right: CGS113 Serge Wave Multipliers CGS65 Tube VCA/Timbral Gate x2 CGS67 Active Real Ring Modulator CGS81 Voltage Processor x5.5 2 … Read More

Here it is, finally wired and mounted in its 8U high EWI Tour Case.  The Quantisise panel wasn’t designed to fit this case; it just happened to (and it’s tight).  … Read More
