Error when upload sketch kstleDrum "ketch uses 7284 bytes (121%) of program storage space. Maximum is 6012 bytes."

Hello!
Help please, when I upload sketch KastleDrum.ino print error

"text section exceeds available space in board Sketch uses 7284 bytes (121%) of program storage space. Maximum is 6012 bytes.

Global variables use 327 bytes of dynamic memory.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board Digispark (8mhz - No USB)."

I have Digispark ATtiny85

when I upload kastleDRUM_CLK_LFO.ino it's OK no problem

How to fix it?

Most probably way too much bloat. The USB bootloader takes tons of memory space. Use USBASP, AVRISP or any other ISP programmer to upload the firmware without the bootloader.
I've used attinycore successfuly for compilation, but don't forget to turn off link-time optimization, it bugs the original code.

Thanks for the answer, upload with arduino nano, through arduinoISP
