Hi Andrew,

Thanks for weighing in.

I tried a couple of variations of that but it doesn't work.  Something to do with the sound being triggered from a bank of partials I think.  Would really appreciate you (or someone) having a look if you have a minute.

Hey Lorenzo,

No one said this was going to be easy:)

Cheers,

Jb

Okay, 

I've not had a chance to look at your patch but the typical method is to use [line], or [line~] (which solves some in-continuity) 

(your target pitch)

[$1 15(

[line~]

|

(your pitch control)

You can make this variable by using something like

(target pitch)       (glide time)

|                       /

|                     /

|                   /

|                 /

[ pack  f  f ]

| 

[line~]

I would also note that 15ms is a very short time for a change in pitch or volume, you probably won't hear an audio incontinuity(click) because of this slide, but you might well not be able to experience it as a pitch slide if it's under around 30ms.

Subject: [PD] microtonal pitch glide using Risset's bell

Dear List,

I have a basic rip of the Risset Bell from the tutorial patches and I can't seem to figure out how to make the overall pitch glide from one microtone to another from midi number 72 to 72.4 over 15ms, for example?

A month old baby and a looming deadline has turned my brain into mush...

Patch is attached (it's for an upcoming performance of John Cage's 'Ryoanji').

All good wishes,

Julian
