So I was incorrect on my description of slide previously. After some further research, this appears to be the gospel of what I'm talking about (taken from https://www.firstpr.com.au/rwi/dfish/303-slide.html):
Since slide is fixed time and not dependent upon the state of CV, it would just be a straight addition to the glide time calculation (if someone happened to have them both on).
Code:
Lets say you have 16 1/16 th notes programmed. Each note occupies
six clock pulses - lets call them pulses 0 to 5.
The gate goes high at the start of clock pulse 0 - the positive edge.
The gate goes low half-way through clock pulse 3 - on its negative
edge.
That is for a normal, 1/16 note. So there are 3.5 clock pulses on
and 2.5 off.
If there is a slide programmed on that note, then the slide circuit
is actually activated on the *next* note. The slide starts at
the start of clock-pulse 0 and ends at the end of clock-pulse 5.
The other function of slide is that the note it is programmed on does
not turn off, but the gate stays high and runs into the next.
Two diagrams. They are wide - so don't let the lines wrap in your
email reader. Also, of course, you need courier text, not some
proportional spaced font.
Firstly, three 1/16 notes. no slide:
Clock edges: / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \
Clock number: 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 0
Note boundary: | | | |
CV: AAAAAAAAAAAAAAAAAAAAAAAABBBBBBBBBBBBBBBBBBBBBBBBCCCCCCCCCCCCCCCCCCCCCCCCDDDD
Gate: __==============__________==============__________===============_________====
Now with slide programmed on note B, which ties it to note C.
Note B plays at it's normal pitch, but it keeps playing.
Then at note C's starting time, there is no new note - as
far as the gate is concerned - because the gate is just
staying on. However it is a new note as far as the CV is
concerned - because it changes to whatever CV is programmed
for note C.
Clock edges: / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \ / \
Clock number: 0 1 2 3 4 5 0 1 2 3 4 5 0 1 2 3 4 5 0
Note boundary: | | | |
CV from DAC: AAAAAAAAAAAAAAAAAAAAAAAABBBBBBBBBBBBBBBBBBBBBBBBCCCCCCCCCCCCCCCCCCCCCCCCDDDD
Gate: __==============__________=======================================_________====
Slide __________________________________________________========================____
So the CV seen by the VCO - which is the output of the slide circuit -
is sliding from pitch B towards pitch C, during note C. We don't
hear the last part of this - since the gate is offSince slide is fixed time and not dependent upon the state of CV, it would just be a straight addition to the glide time calculation (if someone happened to have them both on).
