If you would like a premade PCB to make up some circuits like this, you can use the DB-320 from Scott Juskiw. It is a TL074 constructucted into 4 separate inverting op amps. The resistors from amp + to ground are included to provide the best offset as Dave suggested. You would ha
2004-08-17 by djbrow54
The trick with the perfboard was to get the resistor pattern down so there were no wires. Then it was pretty easy to duplicate since there were eight identical sections. Having said that, I would appreciate a PCB that was setup with a number of duplicate op amp circuits that woul

No, I didn't even draw them out. I used two inverting op amps in series. The first is configured as an adder. Signal at gain=-1 and 15 volts at gain=-1/3. The second is configured as an inverter. I used TL074 op amps. I figured out the resistor pattern for a Radio Shack perf boar

Hi Gary (and other Psimians), IMO, this system has got to be among the premier analog synthesizers in existence today. I know you do a lot of soundtrack work, but do you have any plans of releasing any CD's of original material? If so, let us know if and when you do - I'll be fir

Is there any production module out there that has this functionality? That would be a highly useful module for "frankensynth" types. Cheers, Rob A. djbrow54 wrote: For some of my programs I really need a +/- 5 volt input or output so I just finished building a 1U MOTM-sized set o

Posted in photos is a shot of my Wiard system with the completed console. The 2 PSIMs were modified by Brice to fit in the 3.5 inch deep case. (The PC board is parallel to the front panel, secured by standoffs mounted to the RS232 port mounting hardware). Gary

I wrote a quick little sequencer program that utilizes the PSIM to output a sequence of notes. I have an audio sample of it playing the bass line to Riders On The Storm. I am using the sound command to generate square waves to the aux output jack (the freqout command creates a cl

Freqout works reasonably well when followed by a low pass filter up to about 1000 to 1500 Hz. After that it starts to degrade. The dual frequency capability is nice, though. Dave --- In SynthModules@yahoogroups.com, "Mike Marsh" wrote: > That's it! I'll play around with it some a
2004-08-01 by djbrow54
The highest frequency I can get out of a tight loop toggling the aux jack is 39 KHz. Note the waveform is only 0 - 3 volts on the aux output. The rise and fall time is nearly 50% of the duty cycle. Adding a single goto statement drops the frequency to 34 KHz so there is some room

But doesn't the PSIM and it's Basic support a function (name escapes me at the moment) to produce square wave in the audio range through the Aux out? As I recall, you can get it to actually output two waves, each at it's own frequency, mixed. Some futzing necessary at the output
2004-07-30 by phdinfunk
It seems an attenuator with a hbit of slew might work well. Just a one-pole filter would do pretty good, or a single CyIndustries Lowpass Gate (from the quad).... Then you would get better resolution (or quasi-resolution, as it were) and not have to attenuate everything quite as

hi all. i see that there are various bits of software available which turn the PSIM into an LFO/LFO's. i have a couple of questions about this. firstly, how smooth are they at very slow rates, e.g. if you put a really slow sine on the pitch of an oscillator, can you hear any step

It looks AWESOME! Great job Dave!!! Thanks for sharing it with us. By the way... I may be a bit interested in how you converted the output levels if you wouldn't mind sharing the circuit. I've been running my SC-7 into my Blacet I/O module to get the levels up. Thanks! - Brice --

I chose a gain of 8 based on the maximum output of some of the samples. I wanted the max to be 10 v pk-pk. As such, many of the samples are lower output, typically 6~7 volts pk-pk. I have enough output level but you may want to change the gain to about 10. I also wanted the outpu
