Solid Body Electric Violin & Cello WaveMaps
from ‘The Pickup Test’

For Legacy ToneDexter


WaveMaps for Electric Violins and Cellos

As you know, Audio Sprockets’ ToneDexter Preamp is able to learn the difference between the sound coming from the pickup, and the sound coming from a microphone placed in front of the instrument. It uses that information to create a transformation preset called a WaveMap. When you playback using that WaveMap, it makes your piezo pickup sound like your instrument does in the studio—miked.

Because you can’t mic an electric instrument, it’s been impossible to create WaveMaps specifically for your solid body electric violin or cello… UNTIL NOW!

Jacob Szekely and Luis Mascaro of ‘The Pickup Test‘ and ‘Electric String Player‘ YouTube channel, collaborated with ToneDexter inventor and founder James May to create custom WaveMaps for Yamaha or NS Design violins and cellos. These WaveMap sets are available to purchase from The Pickup Test website.

The Pickup Test site now has ToneDexter WaveMaps available for both electric violins and cellos, the new cello WaveMaps were added in July 2021.

These exclusive WaveMap Libraries were developed specifically for ToneDexter in conjunction with Audio Sprockets’ founder James May. They capture the sound of an Italian violin miked in a great studio with several world-class microphones from Neumann, AEA, Manley and more!

Three libraries are available for the NS, Yamaha SV250 & SV255, and Yamaha YEV violins.

ToneDexter Video – How to Archive and Upload WaveMaps

This video shows how to install the WaveMap sets that we have posted on our Yamaha Silent Guitar page, and these WaveMaps for electric violins. In this example we show how to install the WaveMaps for the Yamaha SLG200N Silent Nylon String Guitar. Install is similar for all the other sets that we have made available.

Transfer WaveMaps

Check out the process for backing up your current WaveMaps and for transferring in new WaveMaps that you download. Remember that you need to rename the WaveMaps with numeric names such as 01.WM or 12.WM and put them in the WRITE folder in order to get them to load. It is good practice to save the download maps, then copy and rename them as appropriate.
