How did you convert and program it to wled?

You need to use a ESP8266 or ESP32 and use a level shifter to convert 3.3v to 5v. Both ESPs are only 3.3v and if the LED is 24v+ and the data line is 5v+ you'll have to shift the voltage from 3.3v+ to 5v+ to go with WLED. But the answer is yes, you can do that. Someone said you can't but I've already done it so that comment should be removed.

Is there a gain control in case my signal isn't strong enough (or too strong)?

The signal strength between the controller and the LED strip is related to two factors. One is the power of the power supply, and the other is the distance between the controller and the LED Strip. They all affect the signal of the controller, if the signal is unstable, it will cause the controller and LED Strip to be uncontrollable.

How many effects can I chain into a show?

The SP105E controller has 200 kinds of dynamic lighting effects.
