Dream IV

Previous - Subsequent

Three problems:  modules are a tight squeeze; one of the power supplies is on the blink; and my Doepfer Envelope is too deep.

A shallower, narrower ASDR would help significantly and I try to pick up a power supply from Maplin on Thursday.

If I am still short of HP, I'll make do with one RVS and take a VS from the spare S/H.

Pitts micro: Dream

Subsequent

The Pittsburgh micro arrived. It is lovely but the cheeks are seriously overpriced: nevertheless, its beauty is confirmed. I'll set it up to run while I finish the build.
I'm tempted to try a Dream Machine in the micro first.

Above is the Strange original, left is the Doepfer version.



The hardware requirements for the original are:

• two random voltage sources
• an 8-step sequencer
• one VCLFO
• one audio oscillator
• one sample and hold
• one voltage inverter
• two VCAs
• and and envelope generator
• the first RVS gets a kick on each 8th sequence step so a clock divider might also be needed.

While I have all the necessary modules, not all of them will fit in the micro, depth 52 mm and 36mm in places. I guess many of the Pittsburgh modules will fit in a Pittsburgh micro and they include a sequencer (14HP, depth 25mm) and a utility module (6HP, depth 43mm) that includes S/H and INV.

This is a thing of beauty, found at Rubadub. I have one small cell, so I'm tempted. I would also like to build something similar on the cheap. The only problem would be the power supply.

[later that day] Couldn't resist it - I bought the cheeks and another empty cell. The cells are quite shallow and so the range of modules will be restricted. When I build a knock-off I'll make it deeper.

The range of modules in a Pittsburgh System 10 is quite tempting at £382, but I managed to resist that.
