Analogue-sequencer

Frank,

Which board revision have you got ?

Are there two transistors Q3 and Q4 for the MIDI output stage ?
Like this: http://www.sequentix.com/build/v1.5/images/cnst-main-small.jpg

Or is it the earlier version where the CPU pin 11 is connected directly to
R5 then to MIDI out ?
