the midi clock stuff is unrelated to the above issue @IvanS is talking about -
right now the clock input of the step sequencer requires the clock signal to go through 0V, the advantage with that is that you can feed it any signal without thinking about offset or amplitude, and it will work. what he wants is to move the threshold form 0V to maybe 0.7V or 1V such that if he feeds it a clock signal between 0V and 5V that it would work without any offsetting or scaling.
If we change the threshold, the consequence is that it now becomes amplitude sensitive, so you cannot use a signal between -0.5V … +0.5V for example as a clock signal. You will have to apply some gain to it.
I don’t think all of this is a big deal but I understand that it might save him some time in having to apply an offset/gain, so if no-one is against it we can move the threshold to 1V. Once that is done I cannot change it back again because we can’t go back and forward on a feature forever.
