Most analog synths *don't* push a lot of energy into the high end, with roll-off caps set fairly conservatively, and 4-pole filters that only open to 18-20KHz as a maximum. Although an analogue ramp might theoretically have energy out to dog-bending frequencies, it certainly won't after it's been through a 4-pole filter and past several op-amps with a 6dB roll-off.

Ideally? Yes. Practically? Not so sure.
