Personally, i think it should be able to continue and you should have
tthe option to do both, i.e. voltage control of the master clock,
which is already there and the ability to select which A155 you wish
to stop start while having sync and the ability to resync. a couple
reasons.

1) since it is the master clock for 1 or 2 A155, if you stop the
clock then both A155 stop. now if doesn't stop the clock , one or the
A155 can continue.

it would be best if there was a way to individually stop one or and
or both of the A155's from the A154. for this to happen, you would
need 2 toggle switches for both of the A155's and maybe a couple of
extra inputs to for VC. the switch should be designated, bottom
position is momentary to sync the a155's to the current position of
the other A155 if it is 2x8 mode, middle position is the on positon
and the top position is an off position.

2) it could clock other sequencers , EG's, pulse dividers etc.


The advantage is continuos clock is that one could

i think the option for both would be great.

again a toggle switch to set the parameters for the one shot mode.
down position for random steps until the last step is adressed.
middle position the number of steps that occur in one shot random
mode cannot be predicted. up position for the number of steps
selected i.e.
2 x 8 after 8 steps regardless of which steps were randomly selected,
the one shot ends and waits for a trigger or reset trigger, same goes
for the 16 step mode.

it is better to have the options now, then saying i wished they had
done them. we are talking about a serious control module here.

I like the idea of an ssm based filter, but it would nice if you
could add new features to it so does new types of filtering and not
just imitate those filters. just asking.

here goes a couple of stupid questions, would it be possible to have
4 separate slopes or vc variable slopes could you also have a high
pass version
