I never use noise. 
If you study the tuning of classic drum machine OSCs you‘ll learn they all use quite low frequencies. But only the upper bands are what you hear. This creates the noisy/fizzy/metallic sound
I listed a few here:

808 cymbal is created by mixing six square wave oscillators with slightly different frequencies, then filtering the resulting sound to achieve a metallic timbre.
If you chain all tracks using neighbor tracks, you can use four oscillators, so I think you can create an 808-style cymbal sound.
Try setting all oscillator waveforms to square waves, adjusting the pulse width (PW) of each oscillator, and then applying a high-pass or band-pass filter on the last track. That might give you a sound close to the 808 cymbal.

interesting, thanks for the reference! isn’t it 5 oscillators btw? (two in trk1, one on each of t2, t3, t4 in the first slot, since the second one is occupied by neighbour osc) I thought there was a filter sweep there, but apparently not. I wonder where tge noisiness xomes from, I guess i need to play more with detuning
btw, I use your a4 mod pack and have been studying how the patches work for inspiration 
Yes, you are correct, it’s 5 oscillators. For typical synth cymbals, the filter doesn’t modulate. As for the noisy part, I’m not entirely sure, but I think it’s caused by the high-frequency overtones colliding, creating a flanger-like effect.
Thank you for mentioning that you’re using the A4 mod pack and studying how the patches work for inspiration. I’m glad it’s proving useful to you

I’ve just posted a YouTube video talking about the A4 as a drum machine for techno. There’s about 16 boots and cats patterns plus maybe 10 ‘perc’ loops starting around 7:30. - https://youtu.be/AqGNq23RdP4
