Applying Portamento

2012-01-26 by dr.jasoncrest

Hello,
I'm wondering what sort of voltages are useful for creating portamento? I have a 16 step melody using one osc & I'm not entirely certain how to apply portamento. Thanks all!

Jason

The slope generator is your friend ;-)
Patch the output of the sequence generator (TKB?) to the input of a slope generator, the output of the slope gen. to the control input previously occupied by the sequence output. That is, put a slope generator between the sequence output and osc input. Set the rise and/or fall times of the slope to apply your desired level of portamento.
Note that due to the separation of rise and fall control on the slope gens, you can have portamento when notes move upward, move downward or both, and can have different portamento rates for up and down.

cheers,
Bill

Hi Jason,

Unless your one oscillator is an NTO, you need to patch the sequencer's melody into one of the following modules:
DTG
DSG
SSG (smooth part).

Patch the module's output into your oscillator's control input and you will have all the portamento you want.

The DTG, DSG and SSG produce varying amounts of lag in an input voltage. Lag varies from a few microseconds to hours, depending on knob settings and CV.

Best

Thanks guys.
Do you know of any tricks to work around using a slope gen? I've got one DTG in this set up and it's currently very occupied. However, I don't need it when playing this melody so I could unpatch & repatch for portamento.

Thanks!

Do you have an SSG?

You can patch exp. or linear glide

So, I've got a DTG & I'm wondering exactly what the correct patch is? I fooled around with it a little bit but couldn't quite get any glide. Fairly certain I was doing it wrong since I was trying to be careful not to disrupt a current patch.

Does your DTG have a signal input?

Re: Applying Portamento

2012-01-27 by BooleanYulian

pretty straight forward:

cv source (seq, midi>cv, s/h, etc..) into signal in of one of the TGs, take it's output to the destination (osc cv in, filter freq, etc...). Set TG's rise & fall fully cw (no portamento), play your source and adjust the rise/fall knobs until the desired effect is reached. Rise will slew the increasing voltages and fall will slew the decreasing ones.

.. a useful trick:

if you want to change the response curve of the slewed or non-slewed voltages, patch the TG's output into the rise/fall cv input and use the cv amount knob to adjust the response curve in the following manner (if i remember correctly):

- 12 o clock = lin

- fully ccw = exp

- fully cw = log

hope this helps

To clarify a little, STS has offered the DTG with different options. In one, a "cycle" switch occupies each of the two "middle" jacks just beneath the blue outputs. Another has jacks for signal inputs, like the DSG. Yet another has jacks for bipolar outputs in place of inputs or switches. Did I miss any?

Don't forget about using the filters! VCFQ in low frequency mode is pretty normal portamento and can get wild in regular frequency range with some resonance! VCFS also works for portamento although it's a bit different flavor.

Have fun!
