  Subject: [Simmons Drums] SDSV - presets only


    Hi

  I've got an SDSV !!!!!

  It's seen some action in its long life. The outer case looks very battered. It's the standard bass / snare / 3 x toms (no cymbal, no hihat!).

  The problem I have with it is that I can only use the factory presets. On the bass, snare, tom 1 and tom 2, I cannot even select any of the other three "channels" for each module. For tom 3, I can select the others, but as soon as I hit the pad and trigger the sound, it reverts to the preset channel. (The non-preset channels all work on tom 3 - and I can get some amazing sounds out of it - but only if I hold one of the four buttons in - bad for my drumming technique...).

  Has anybody come across this problems before - or have any ideas how I could fix this?

  By the way - the presets may not be cool, but wow they sound incredible. So much depth to the noise being made. I'm triggering them from some SDS-800 (mk 3, mk 4?) pads via the Synth In jacks - thought I might have difficulty, but with the sensitivity turned up, the SDSV is triggering perfectly.

  Thanks in advance for any advice you can offer.

  Aaron

    Hello all and hello to my friend Michael!

  Yes Michael is rigth,on the SDS5 sound selector is missing a pull down resistor at the clocks input pin 3 and 11 (they are tied together ) of the 4013 dual flipflop.And I wonder how it was working without (CMOS input should not stay no polarised like you could with TTL input that have built in pull up resistor).
  I have to put these resistors on my SDS5 that have trouble changing preset (but perhaps the push buttons contacts are also dirty???)
  Michael,you have really good improvment with TL084 instead of LM324???
  I know that TL074 have a really better slew rate than LM324...
  I will try....
  See you soon all

    Michael (not god - but very close)

  Thank you so much for this help - you're a star, and I'm very grateful.

  My electronics skills are pretty basic so I will need to find somebody I can trust to do this - I would not trust myself in case I damage the modules further.

  Love my SDSV and love this group too!

  Kind regards

  Aaron

  Friends on the swedish analogue list "SAS" BBQ'd manuals for digital 
  synths a few years ago. A statement and a lot of smoke too... manuals 
  for digisynths tend to be thick! :D

  Some feedback on the pics:

  MusicAid logo on the shirt... nice! German juice is not my favourite 
  though. Bloody "multivitamingetränkt". :)

  Cute SDS-3 clones. Individual LFO:s I guess?

  IKEA Helmer kicks ass as storage for electrical sensitive devices. Guess 
  who's got a yellow for proms and disks etc. I've toyed with the idea of 
  getting a black too and mix the drawers for more Waspy feel. 8-)

  Snakeskin pads... scary as hell!

  Lovely old square wave generator on the last pic. Those were the days! :D

  Sounds interesting. "The Buchner SDS-3 Trap" :D

  When my synth arsenal began growing I used a lot of Niklas, but has
