[sdiy] sn76477n + control voltage

[a]

Hi

I'm currently working on a junky chaotic synth box with patchbays, 
utilizing 4558-opamp based LFO's(because I have about 30 of them), and 
for VCO's I'm using a 555 and an sn76477n. the output cv from the LFO's 
enters a JFET transistor hooked up to 9V to control the 555, but for the 
sn76477n it demands 5V instead of 9V... in order to control the sn76477n 
would I be able to just use the same JFET system as I'm using for the 
555 but hook it up to the sn76477n's 5V output instead of the power 
supply's 9V?

PS here's an ascii diagram:
