Spin Semiconductor

A stompbox based on FV-1 is available here: http://www.tonepad.com/project.asp?id=68 But I wonder about the input sensitivity of this board. Shouldn't there be an input gain stage (with gain > 1, especially if you want to use it with a guitar)? Otherwise, you could get high noise level. Is it right,...

I suggest making Google search on "impulse response measurement software". You will find a lot of responses.

I wouldn't expect much since it uses ATtiny45 (which has nothing to do with DSP). It's rather a toy and not a studio effect.

Kradsith,

Can you post your code? I heard that the Cylon voices were generated with EMS Vocoder and a ring-modulator and I'm curious to hear your results.

I need an idea to measure input signal (without an osciloscope :lol: ). It would be great to measure RMS value of the signal and to generate let's say sinus signal on one of the outputs. The signal would be measured with a simple multimeter. Does it make sense? I need to to find out what is the sign...

I have a difficult question. Is it possible to detect input signal tempo (let's say a guitar plays quarter notes) and use this tempo as a parameter for an effect (e.g. chorus or delay)? This could be an additional, "virtual" potentiometer to be used with FV-1.

I've got the board from Profusion. Program #1 (#2 seems to be the same).

Is there an easy way to tell which programs are stored in the EEProm on SPN1001-DEV? One of the programs is a nice, long delay but I'm not sure which source it is.

I'm confused with the description of the GA_DEMO board (and the photo on your Web site). The list of programs does not seems to match the descriptions on the photo. There is also a program called WAH, which in the designer's notes is mentioned as a test program (not to be used).

I assume that there are 8 internal programs in the Development System. The installation package installs only 6 programs. It seems that at least the SUB_BASS program is missing (which I would like to look at). Is the program available on your Web site - I cannot find it? Which other program is missi...

This is my first post - I'm not sure where this question should be asked.
I'm trying to contact you regarding development board distributors (possibly) in Europe. I sent several e-mails but there is no answer until now.
Is SPN1001-DEV distributed in Europe?
