i think the best method to clock the A155 from midi, would be to use 
the A190 instead of the A147. this would provide a tighter clock. the 
only function it does is provide a steady pulse for the A155 clock 
input.

remember the A147 is a resettable lfo and it is constantly looking a 
reset trigger. this could produce anomalies as a clock source if you 
are syncing to midi. i think the A147 is better used for controlling 
voltages to sync to note intervals or measures. i.e. syncing a filter 
sweep to a specific note lenght or bar measure. also you could a 
keyboard voltage to play the A147 to trigger the A155 clock.

you could place the A160/161 right beside the A154 to sastify 
function.

you could use the A155 bottom row cv out to control the pulse width 
cv in of the A154. not sure if this could work, but highly probable.

 but maybe someone else has

 i believe the clock cv in is specifically for that, what i find 
confusing is having a cv pot on the clock cv in. could this behave as 
a divisor for the input? Dieter? Bakis? Anyone?
