  1. I'd never heard of Hz/Volt, but had not been exposed to Korg or Yamaha stuff, being only with "home brew" stuff in my teens. One useful property of silicon transistor physics is the exponentional relationship between base voltage and collector current. When calibrated, every volt increment gives a doubling of collector current and hence an octave shift in oscillator pitch. So easy to implement but very temperature dependant which needed a solution. One of which was to build a heater inside the chip which held the temperature at some higher value probably 70 - 80C. The second generation MiniMoog oscillator circuit used 78.4C
  2. My guess is the weak signal appearing on the jack is to trigger the internal envelopes and an external signal of normal spec can over ride it. Othewise a int/ext switch would be needed. Could use a switched socket - but a less reliable component. Before I went down the Behringer route, I thought of building a full size copy of a Model D panel, with rotary encoder switches in place of pots (Incidentally "two-knobs-per-finger" is genius). The encoders would be read by a microcontroller and fed into a Arturia Model D software via Midi, the Arturia has a feature to assign Midi commands to controls (but not sure if all controls can be programmed this way). Microcontrollers being the bread and butter part of my life, I'm not a Musician.
  3. I got a Behringer D when they were released, but being a 'patch junky' added some extra Behringer modules. I posted this elsewhere: http://www.hut-six.co.uk/Synth/trigger.html On Emerson's Modular, I remember a few videos of early ELP where Keith went to the modular and did not get anything like the expected sound and spent a few seconds turning knobs. There is one on SkyArts, which is ridiculously colorized in placed.
  4. Don't they have a UFO problem there? Stray magnetic fields. Or it could be the Northern Lights magnetic storms.
  5. SORRY that should be connect meter between RING and SLEEVE !
  6. Ibanez EHB1000 (new toy) measures 1.3mA. Might be worth trying the Energiser Lithiums but looks like you have a higher drain active. Anyone else measured the current? Easier way is get a Stereo plug and connect current meter betweet ring and tip. That will turn the bass on.
  7. Only ever had a SR500 active bass. Seems hard to flatten the battery (but did not leave plugged in on standby). I read a little under 1.5mA using same method, so a lower drain bass. It is pushing it a bit to design electronics to run on 9V, 18 would be better. So rechargeables, NIMH and Lithiums are too low a voltage for a 9V circuit to function as designed. Incidentally, I bought a "trail camera" a few years ago. It came with some Energiser Ultimate Lithium batteries and these were recommended by the manufacturer, worked better than Duracells which were rubbish. It was the highest spec Energisers. These are not rechargeable so you get the full 9V, higher capacity. might be worth trying but maybe 6mA is a high discharge bass. I have a headless Ibanez, I'll get it out and measure it
  8. I think Fender admitted it was a problem with bolt on necks a while back, and they had no solution. But I heard there was a headstock clamp affair. Also Tungsten slugs fitted under the tuners. ? I had noticed neck resonance can also vibrate open strings if not muted (if 4th or 5th) I suspect laminated necks don't have this problem, being more rigid. Just bought a concert ukulele and f# is quite dead but it is a bit of a plunk, plunk sound anyway.
  9. Odd how the cameraman has problems finding the bass player, always happens.
  10. I find this a bit sombre (but good). Written just after WW1, Elgar had lost friends and horses and was not living at his beloved Malvern
  11. I quite like Davy Graham's version and his title "She moved through the Bizarre"
  12. Did anyone catch the ELP December 1970 Lyceum film - was a few days ago now. What a mess, totally ruined by the psychedelic overlays. Early historic ELP film ruined. But I guess there are few dinosaur prog rockers on here!
  13. I did not even enroll on this course and they awarded me an MSc.
  14. Lead free soldering is pretty rubbish compared to old lead/tin. I built an 18W valve amp lead free, had quite a few dodgy joints I had to re-solder. Guitar soldering always looks a bit rough anyway.
  15. I love passive basses!
  16. Only way to go
  17. Everything is carcinogenic in California. Can't remember what I bought recently - but it had a warning.
  18. The price will be new.
  19. There have been a number of similar raffles over recent years, probably one a year, with a restored MiniMoog each signed and donated by a esteemed musician. Most seem to be primarily keyboard players. Who knows?
  20. It sounds different again when passed through a low-pass filter.
  21. Buy a ticket, you know you want one.
  22. iPhones? https://www.greenamerica.org/end-smartphone-sweatshops/tell-samsung/apple-soars-workers-suffer
  23. Yes, they even copy Alien UFO's
  24. I thought they only did Angle Grinders and MIG Welders.
  25. Someone should market string gunk, as James Jameson said "The Gunk keeps the Funk".
