If I remember the SR16 correctly, the answer is sadly, no. The SR16 will let you assemble a series of patterns into a song like order, but it won't link them. You'd have to change patterns when needed.
This is just a hint as I was unable to find the schematic. Transformers VERY seldom fail, if you are getting anything out and the fuse is holding with no heating, the voltages are probably right.
Common voltaages seen after the rectifier and filter and regulators are +/- 15 volts and sometimes +5 volts. For the power amp they are usually between +/- 35 and 60 volts unregulated.
For small amps using the TDA2050 type amps, you will see aproximately +/- 24 volts DC unregulated.
Chances are you have NOT got all the bad parts out yet.
HINT: While cold starting an amp after it smoked, put a 150 wat lamp in series with the power cord to act as a current limiter... saves fuses and parts.
The DDT circuits PROBABLY look for amplifier DC balance AND no overload of power supply as protection.
They COMPRESS the audio when it goes above a certain level.
SO, to troubleshoot this you will probably need an oscilloscope.
LOOK for a supersonic oscillation that you cannot hear but MAY be driving the amps beyond the DDT trip point. Drive a pure low level sine wave into the amp and follow it through to see at what point the DDT compressor senses an out of range level.
Remember it HAS worked before, and there is still a bad part in the unit. DO use my suggestion to limit the current as often while troubleshooting this type problem, the signal will suddenly go to a point to fry something, then you get to replace all the parts AGAIN.
