One of the coolest effects that we have recorded thus far has been achieved by using the roland vocoder. It took a lot of getting used to, as the signal path was quite confusing, but we were able to get the hang of it. We created an auxiliary track in PT for the guitar track that we wanted to use as the vocoder music input. Sends were created from the guitar tracks to the new aux and sent out to the patch bay. From here, a TT to TS was used to send the signal into the vocoder's line level at 0dB. We used a 57 and plugged it into the microphone input on the vocoder to act as the vocoders 'voice trigger.' The microphone level was set to approximately 10 o'clock. The wet/dry mix was set to fully wet to ensure only the vocoder's sound was being heard and not what I was speaking. The volume was set to approximately 3 o'clock. The frequency adjustment had the biggest boost in the mid range, or between the 6 and 7 knobs. The lows were almost nonexistent and tapered off below the 6 knob. Above 7, 8-9-10 were around 0dB, while the knob 11 was fully 'off.' We used the 'Vocal Amp' output with the level selector at high. A quarter inch was taken from the vocal amp and into the millennia; from here the signal was routed through the patch bay and back into PT. A new 'voco' audio track was then made in PT to record what we were hearing from the vocoder.
It took quite a while to get used to tracking with the vocoder, as the guitar part that we were recording with was very syncopated, which isn't an ideal sound. In the end we used a couple of short phrases that went along with the lyrics of the song for a powerful birdge section.
