Hello everyone! i want to get into eurorack ,but do i have to get a sequencer to "play"? Or is there another way? Without keyboard. Thank you!


There's many ways to 'run' a modular patch. Sequencers, random modules (wogglebug, Turing Machine, etc) touch plates (pressure points, Sputnik touch keyboard) or even midi-CV modules such as the uMIDI from intellijel.
It depends on the type of patches you want to make.


Can i use just cable. Like. vco > effect > effect > mixer? Without keyboard or sequencer ?


You will want triggers to make thinks happen and control voltages to define pitches to be played by your oscillator/s.
Any module/s doing that can play your patch. For example, a LFO can be used to trigger an evelope that shapes notes out of your continuous OSC output. The same CV from an LFO (or an envelope or other CV source ) can be used to produce pitches for your OSC, combined with a quantizer to cut steps in your gliding OSC if you want to play musical scales. So yes, no keyboard or sequencer needed.

If you just want drones, by all means. Then your patch will simply depend on your manual control and processing.
