	Hey hey, I'm trying to get proper portamento with tied notes working. My pitch is in the instrument's p4 in pch oct.pch format. But I can't get it to do a proper slide: ... istied tival kpitch = cpspch(p4) tigoto Tied ... Tied: if istied == 0 kgoto Play kpitch port kpitch, .2 Play: aout oscil 1, kpitch, isine I tried using different variables, i.e. kbasepitch = cpspch(p4) ... tigoto Tied kpitch = kbasepitch Tied: if istied == 0 kgoto play kpitch port kbasepitch, .2 ... I also tried performing the port on p4. The pitch always seems to rise from 0 not from the previous notes value. What's the proper method, please?

	Hi, I think you can use an extra argument to the filter (port) to set how it is initialized. Using a negative value will skip initialization, and then it should start from the previous value. This should do what you want. Like this: kpitch port kpitch, .2, -1 Øyvind ons. 5. jun. 2019 kl. 21:37 skrev Jeanette C. <julien@mail.upb.de>: Hey hey, I'm trying to get proper portamento with tied notes working.
