Bass signal to MIDI

[unclefu]

Hi everyone!

I'm playing in a trio (vocals-guitar, bass, drum) and I thought about widening the rhytm section, especially during solos, by doing something with the bass. More than just distortion, which I tried before, something better, like sending the bass signal to some kind of midi recognizer tool, which allows me to do anything I liked with it, played parallel to the original bass guitar sound, thus widening the riff during the solos.

My question is, are there any good devices for such recognition, and what are they? As far as I know, there are three major problems with the tool, first is recognizing two notes played simultaneously, I think it's because it uses some sort of Fourier-transform, picking the lowest component of the signal, and the lowest component of the two notes is the same as the lowest of the lower note. Second I think is recognizing in which octave the note is, I guess that comes from the wavelength being the multiple of an octave higher one. The third one is the latency which at a bass guitar tuned in E is probably around 24ms, the wavelength of the lowest note.

Are there any devices that can deal with the issues mentioned above?

sonuus B2M bass to midi converter maybe???

edit: its only monophonic , sorry...

 

[unclefu]

Yeah, it's monophonic, and also, I saw this video:



It often makes mistakes with the octaves.

not quite a plug and play option but :

i think pairing a roland GK-3B with a roland VB-99 could do the trick....

on the expensive side but have you considered a midi bass??
if moneys no option :

Whoa, that's one big fat price Thanks anyway!

Cubase has a audio process that converts monophonic lines into midi.

You can sorta do this in Reaper. I tried it once with guitar....it's not totally accurate and I forget exactly how I did it. I think ReaTune.....might work a bit better with bass, but I'm not exactly sure the result you are after.

 

[unclefu]

Yeah, but these can't be used for live playing. I'm gonna stick with some sort of distortion instead

 

[MindMunch]

Yeah, but these can't be used for live playing. I'm gonna stick with some sort of distortion instead

Oh, is it for live use? In that case Melodyne won´t work.
I think you better stay away from MIDI and just put a splitter sending the signal to guitar amps and weird effects, like the Death From Above bassist do.

 

[unclefu]

Yeah, that's what I've been planning if the MIDI thing doesn't work out. And I guess if you don't want to pay zillions, you have to face some tracking and latency issues, which wouldn't be too cool, so yeah, maybe I'll stick with the effects. Thanks for all the answers!

You could do the Geddy thing and play moog pedals with your feet. It does'nt seem that hard

have you tried the sonnus guitar midi converter for transcribe guitar to tab?

when you say monophonic it means that when you play a chord only one note is transcribed?
