  Hi Pigletdad40,
  if you have a tomcard, it's possible to convert it into a hihat. There are
  some empty gaps on the drumboard (card) which must be filled with some
  additional resistors, capacitors and diodes. There is only one eprom
  responsible for both open and close sounds, the pedal regulates decay of the
  vca and triggers also the env generators. The SDS's HH is, by the way, one
  of the best playable and sounding HH's available. Open, close, half, chick,
  stomp, splash, very nice. Invented 20 years ago...

  The SDS5/SDS7 pedal itself is constructed around an infrared interrupt
  switch, a H21A1 (Google around for details). It is definately not possible
  to use other pedals without modification. The Hihat XLR of theSDS7 outputs
  15V on its Pin 3. There is Gnd on Pin 1. And Pin 2 is the input of the HH
  control-voltage. Using switch-pedals will result in shortcut of the SDS7
  brain.

  To increase sampling time, you can modify your new HH-card to 64K and
  download the long HH eprom from www.simmonsmuseum.com.

  So, if you made your decision to convert a card, I'll give you all details.
  Michael
