Re: [PD] SOLVED!!! Re: pitch to voltage SOLVED!!!

roman, thanks for your inputs. i tried both fexpr and expr and sticked to fexpr at some point, don’t know why though. will change it back! (i remember reading that fexpr was more expensive but also more precise) to make the whole thing work with real world signals (bass guitar in my case) you

Re: [PD] SOLVED!!! Re: pitch to voltage SOLVED!!!

That works very well. Good job and thanks for sharing! One minor thing jumped to my eye: Your patch uses some instances of [fexpr~] and all of them actually don't need [fexpr~] functionality. I experienced that [fexpr~] is quite expensive, which seems apparent considering it is designed for feedba

[PD] anything pd related happening in NYC from May 19-27?

or unrelated? electronic music shows, analog or digital. let's hang out and stuff. Will there be a patching circle in May? -- www.epicjefferson.com ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinf

[PD] SOLVED!!! Re: pitch to voltage SOLVED!!!

hey miller and list, find attached a version that works beautifully. it's a dirty hack without upsampling but it works extremly well. don't ask me why, i have no idea. thanks for all the help miller, really appreciate it! and thanks for pd in general :-) cheers, simon sinetosawtooth.pd De

Re: [PD] How to read I2C sensors?

Check out also pd-l2ork k12 documentation where you can learn more about "lots of pots" RPi shield that gives you essentially 8 capacitive channels via the aforesaid mcp3008 d/a chip. This is what pd-l2ork essentially supports out of box. To access k12 mode start it with appropriate shortcut or s

Thanks Ivica, I'll check out pd-l2ork. I might use a Raspberry Pi for that purpose anyway. I need some capacitive sensors that work without actually touching them. All I found was using I2C. Ingo Von: Ivica Bukvic [mailto:i...@vt.edu] Gesendet: Sonntag,

Re: [PD] How to read I2C sensors?

I forget what i2c uses driverwise, but if it is spidev, in pd-l2ork you have disis_spi external that allows for reading data from mcp3008 8-channel ad converter. The external is specifically designed for Raspberry Pi build of pd-l2ork, but I don't see a reason why it could not be compiled for vanil

Actually I don't know where the change~ object is from - I've nver seen t before. I would just use biquad~ 0 0 1 -1 0 (assuming that change~ simply ubtracts the previous sample from teh current one as I guessed from the patch :) M On Sun, Apr 27, 2014 at 03:40:01PM +0200, Simon Iten wrote: > ok

[PD] How to read I2C sensors?

I have been using an arduino with [comport] (pduino) to read out sensors so far and want to use a I2C sensor board for some other sensors soon. Can [comport] connect to the I2C interface or is there another object in Pd-extended that can do that? Thanks! Ingo ___

Re: [PD] pitch to voltage

so if i would measure at the peak of the sawtooth and would upsample inside the pd patch, i would get higher resolution, right? any ideas how i can measure at the peak? (using the rpole output on both samphold inputs does not work and delaying one of them is also not working) which i would hi

Re: [PD] pitch to voltage

Sorry for the double answer, but this also occurs to me: To improve accuracy, measure both halves of the cycle and add them. To improve further, upsample the whole mess, say by a factor of 16. Doint both of those would improve the theoretical resolution by a factor of 32. (Of course, you still ha

Re: [PD] pitch to voltage

That is an excellent, witty way to measure pulse withs using only tilde obects - my hat's off to you. The methond only has limited accuracy since its measurement is in samples. For instance, a 1/2 cycle of a 440-hz. tone at 44.1 kHz is only 50 samples, so there's only 2% accuracy. That's about

[PD] pitch to voltage

dear list, i have a strange problem with my “sinetosawtooth” patch. it is basically a version of the pitch to voltage conversion used in the old gr300 guitar synths from roland. i cut out all the clutter to make it easier to look at and understand. (cut out the adaptive filtering at the input
