Hi there, first post....so, hi there, hope this is the right section for this thread...
I am looking for people to contribute ideas or develop this project in the circuitry department...or at least give clues as to approaches one might take for this kind of project/design...
The idea is for sensor on the low 3 strings of a guitar. I have developed such sensors which are low impedance that can sense individual strings. The intention is to send them to an output and drop the signal by an octave using a pitch shifter or similar effect. A preamp to boost the signal will also be required.
The circuit help is required is about 'logic' for want of a better word. The end result is that I want to only have the lowest note of a chord sent to it's own output.
So if we label the sensors E6, A5, D4 for the low three strings of the guitar, low to high. If E6 is sounding I want this to turn off A5 & D4. If E6 is not sounding, A5 to out and D4 to be turned off. If lower strings are not sounding, I imagine there is no harm in leaving them 'active'.
So, any ideas to achieve this kind of thing. Needs to be low noise, simple and compact and low power requirements. My intitial thoughts are some kind of electronic switch, perhaps a transistor that will sense the incoming signal from say, E6 and turn off the signal to a preamp from A5 and D4...that kind of thing.
I have a bit of electronic experience and can solder basic circuits and such, but more of a concept guy and not good at the details nor know quite the technology that might be appropriate and keep it all 'happy' for such a task. Power is likely to be from a 9v battery. Quiet and low noise characteristics will be essential as for any audio circuit. Small and simple and low power drain will also be necessary to be practical.
An example of the kind of 'sound' one might get or to clarify the 'intention'. Guitarist 'steven king' uses a magnetic pickup on the low two strings simulaneously and the sound created can be found here... http://www.guitarbystevenking.net/King_CD_sound_clips.html
I can do this kind of thing with a pair of active 'sensors' but there are some compromises in this kind of approach. The two low strings are always on and so low as to sound musically 'muddy'. Many octave dividers are not ahppy and will glitch with more than one signal at a time, the octave drop is always on these strings so one needs to ensure that the tunes arrangments do not hit both as these low notes tend to sound 'muddy' and perhaps glitch things as well.It relies on finding teh bass notes only on the two low strings which can create large stretches for the player to reach and so another string would be an advantage for the player.
In case it is not obvious, the guitar will have it's own output/pickup system for all strings like a conventional instrument an that these low notes will double the normal octave sound of the instrument. The purpose then of this idea is to send out a separate output of the lowest string being played alone to be processed separate from the rest of teh guitars output.
So, any help, ideas or direction to aid achieving this kind of result would be appreciated....thanks in advance...
