APPENDIX 2: ECHOMATIC II CLASSIC AND ROLAND RE301 EMULATION DETAILS
These two emulations do not use the
P2 control as a ‘switch’ to select a ‘Heads Program’ as is the case
for the other emulations detailed in Appendix 1. Instead, P2 is used as a 0-100 variable control.
In the Echomatic II Classic, which had four heads, P2 controls the echo level from Head 4 (H4) with P1
controlling the echo level of Heads 1, 2 and 3 together (H123). P3 controls the feedback, which is taken
from Head 4.
In the Roland RE301, which had three heads, for this emulation P2 (Vari) controls the speed of the
virtual motor and hence the delay times of the emulated heads. The RE301 had a number of ‘modes’
with various head combinations selected by a six-way MODE switch. This emulation simulates Mode 5
(Heads 2 and 3 selected) with feedback from both heads.
