The wiki says 2CVTOOL IN can take audio signal. Would it amplify it like 2SIGNALAMP? Can please someone with both modules make some comparision with amplifying triangle wave from VCO?

The 2CVTool does not amplify your signal, only let's you attenuate it or invert it (= make it smaller or swap it upside down). The human ear cannot hear inversion or offset for an audio wave. However, if you apply offset or inversion to a control parameter (eg invert the modulation of filter cutoff), that you will hear as something different.
Attenuation is easier than amplifying. I run into the same problem: the square Waves are very loud and the Triangle is too low. However, i think the easiest solution is to turn down the volume of the square (=attenuate) and turn up the overall volume in the end.

Thank You keurslagerkurt It was very helpful. I usualy adjust the volume to the level of most quiet component, just as You've mentioned and sometimes I run triangle via Wavefolder to makeit louder but was thinking about other solutions and currently planing to buy some modules, so need to determine which I would need the most at the moment. |

Glad I could help!
Yeah, it's def a downside of the squares being generated by logic chips (they go from 0 - 5V, so max volume of AE). Often when I'm already patching for a longer time, and I want to incorporate a triangle wave later on, its just almost 'impossible' to make it work. I think the SignalAmp is a good idea for this, but I do not have the module myself so can't test. Or if you have the braedboard, it would be an easy circuit to make with just one MCP602 and a few resistors.

I think I'll buy SignalAmp eventualy as I also plan to experiment with external sound sources like contact mics prepared guitar etc. Don't have the braedbord module.
