Following the blinking LFO light on a hardware synth
This is a fantasy project,
The synth is a Yamaha CS-5, although if i got it working i’d also try it on my fender rhodes which also has a blinking LED.
The light turns off and on to show the rate of the LFO.
Can i set up a light sensor or camera and a Max patch that measures the rate and either outputs a number in BPM or drives an LFO that matches the LFO in the synth?
any thoughts? x
this should be doable with a cam and jitter i guess. Another thing to consider would be to pull the voltage applied to the led out of the synth and analyse it directly. Then the use of [timer] would be straightforward.
thanks for your reply,
as to the voltage from the LED, it did occur to me, but i hesitate before taking apart my synth? i don’t suppose there is another way to "pull the voltage applied to the LED out of the synth",
assuming i managed this – being new to max – how would one use [timer]?
My nephew did something like this, but to synchronize its pedals, delays, chorus and other time based effects .. even a cute envelope follower whose light increases as a function of the amplitude.
What did I think I should ask him directly, but can not receive or make calls from El Chino and I think this week is in isolation.
I think: Led Photoresistor (LDR) and a microcontroller, probably an arduino or something based on ATMEL …
The information collected in the arduino is processed in this wonderful, wonderfull application.
If CAM>jitter.. If i wanted capture all the lights… I think hmmm the fps per second…

Thanks Wendy, naturally my heart beats a little faster thinking that you are the Wendy Carlos, who still inspires me (switched on bach), but this being the internet i suspect you have just taken the name,
either way, thanks for your response, i almost bought an arduino and light sensor yesterday- but i’m hesitant, more research required, should you manage to contact your nephew please let me know,
So is the internet, my dear, one can not be sure of anything.
I’m glad you’re on track.
If you’ve got a cam, I would first try the jitter road with a high rate metro.
I’d never do this with a cam, the photo resistor thing is just so much more convenient IMHO
i’m open to both options, anyone got an example of a jitter patch that would do this?
…and if it is the real Wendy Carlos, so pleased that she’s using Louis Wain’s ‘Electric Cat’ as her avatar!
