MS20 completed & some sunshine. Long walk around Helvellyn.

 The week started warmly so I got into the garden and started clearing a few areas, mostly to give me access for rodent assaults. Yeah, that time again. Tony has done my MS20 and it looks a gorgeous job from the pix. Interestingly he put all the mods on the left hand side rather than the right where I'd expected. (the circuit board he added needed to go somewhere). Will get up there and pick it up soon - John's Wasp is gonna be a while yet. 


For any nerdy readers, these are the mods: 

1. VCO Sync switch.

2. VCO2 FM Level pot and socket, plus raw output (the selected wave)

3. VCO1 saw, triangle and pulse output sockets.

4. VCO1 PWM input socket 

5. VCO Mixer. Two additional pots and sockets.

6. EG2 positive output and (minijack) V-Trig out

7. Change colour of all LED to green and dim brightness.

8. Filter Mode select switch.

9. VCA & VCF envelope source switches.

10. VCA gain pot. (Odyssey drone mode)

On a regular MS-20 the sustain level interacts with the decay at fast decay times which changes the shape of the decay at different sustain levels. But this one doesn't any more. The Korg also produces an EG2 output that centres around the sustain level. Rarely useful - so it's defeated here. Interesting MS20 factoid: EG1 actually goes from -5V to 0V.  Had to compromise on a couple of mods due to the lower power of the newer MS20s but these will do nicely.


Hmmm seems we're sticking to inverse video ;) Anyway that's the Audion cover test with my playing my Pipe. Should do an all-green gig with MS20, System 8 and Pipe.

Wrote objection letter for housing development on the basis of the increased risk of flooding. Pat off to get new cooker as ours was on fire last night.






Solstice...
Tim and I drank in the sun, met an SAS guy, you know how it is.





Hellvellyn tomorrow (via wimpy old man route)
