Sure.

As only 2 oscillators are used you may well only use one engine on synthv1, either "Synth 1" or "Synth 2", by turning the OUT Volume to 0.0 on the chosen one out.

Now you already know how to have a triangle wave: DCO Shape 1, 2 = "Saw"; DCO Width 1, 2 = 50.
Tune on -2oct means both oscillators are tuned 2 octaves dow, so set DCO Octave = -200.0.
Mix on 0db 100% means that both oscillators are balanced, so keep DCO Balance = 0.0.

Turn the LFO off, it won't be needed as from the generic patch above.

For the Low-pass filter you should simply keep DCF Type = "LPF" and DCF Slope = "12db/oct", then set DCF Cutoff = 100.0 and DCF Reso = 0.0; as there won't be no filter envelope, you should turn to DCF Envelope = 0.0 and that's all for the filter stage.

Now comes the tricky part :) the Amplifier envelope (DCA in synthv1)... you may set DCA Attack = 0.0 (A) and DCA Sustain = 0.0 (S) already.

The big question now is how to set the 0.12s value for DCA Decay (D) and DCA Release (R), right?

Ok. Look the current value of DCO Env.Time, which makes for a percentage (%) of the maximum running time of each stage, which in turn is hard-coded to 10s, which means that, for a current value of DCO Env.Time = 50.0, makes it for 5s in total per stage. From this simple calculation, 100 * 0.12s / 5s = 2.4, gives the correct value you should set to DCA Decay = 2.4 and DCA Release = 2.4.

Wasn't that easy enough?

Hope that helps.
