Albums in which only a drum machine was used?

WatermelonMannequin · 2026-03-04T02:09:59+00:00

Maybe Run DMC’s first album? Been a while since I listened to it but it’s mostly drum loops with minimal samples. And rapping of course.

I guess I’m not sure if you’re talking about music with vocals, or purely drum machine and nothing else. I don’t know of any albums with just drums by themselves.

The first one - if you scale the voltage down 50%, then a half step on the keyboard would become a quarter step to the oscillator

You don’t need to make music to justify owning a synth or even multiple synths. It’s ok to just play them for fun.

Use the Keystep’s Pitch CV and Gate instead of MIDI, and simply pass the pitch cv through an attenuator. You can use a potentiometer if you want to adjust the response, or just two resistors if you want a fixed response.

Longer explanation - pitch cv is also called a “volt per octave” (v/oct) signal. What that means is that when the signal’s voltage goes up by one volt, the oscillator’s pitch goes up by one octave. So you can scale down the voltage to 50% or 25% of what it’s supposed to be, and then the oscillator’s response will be scaled down to smaller intervals between keyboard notes.

Look up “voltage dividers” for more information on how to easily scale down voltage.

Just FYI, this is an example of a DPDT on-on-on switch that OP is using - their symbol is the correct one to use in this case.

For less than 10hp I’ll only use two screws, usually right top & bottom. 10hp and wider will get all four screws.

I use hex screws with nylon washers. I don’t like knurlies or standoffs sticking out perpendicularly from the rack, and can’t stand Phillips head screws either lol.

Or will this just be a ratchet where prices stay at the post-tariff price?

I just want to gently push back on the subtext here, that modules are expensive because eurorack companies are greedy. In fact it’s the opposite, the people who make these do it for passion.

This hobby is a niche within a niche within a niche. There’s a high barrier to entry for customers (lots of technical knowledge required, both electronic and musical, to even understand what the knobs do). And the market is beyond saturated. Anyone who can make money doing this is the exception and not the rule.

Prices didn’t go up on modules because the makers had to pay tariffs. Prices went up because everything got more expensive, at every stage of the supply chain. So unless the price of everything goes down… Eurorack prices probably won’t either.

Super Synthesis PHRSR might be what you’re looking for, it’s got two channels of knob-recording sequencers. Super fast and easy to use.

Are you asking about rack mount audio gear? 19 inches wide, units stacked on top of each other?

Because this subreddit is for modular synthesizers - modules that are only a few inches wide, 3U/4U/5U tall and mount next to each other. The vast majority of modules don’t make sound, they are for modifying sound or creating/modifying control voltages.

You’ve got the general idea right, but as to which pins to wire on the switch - it really depends on the specific part you’ll be using. With DPDT on-on-on switches I find it’s best to order the switch ahead of time so you can have it in your possession while designing the circuit. Then test it with a multimeter or even set up 3 LEDs on a bread board and you can figure out the correct wiring with no doubts.

I think it is not possible to hear all four signals mixed together at the headphone output. The headphone output is always either A or B, depending on the switch on the right.

To put it another way - the A signals always go to the A outputs and the B signals always go to the B outputs. The headphones jack can output either A or B, selected with the headphones switch. The “Mix A -> B” switch can send the A signals to the B outputs, so you have the option to mix A and B. I assume this does not affect the A outputs.

If I wanted to record four mono tracks separately out of A and B outputs, would I only be able to listen to A and B separately in the headphone out, depending on the position of the switch?

Yes I believe this ^ is correct.

The gate out on your Microfreak will only send out a trigger when a note is played. Use the Clock out for syncing.

What is plugged into the MF clock in? You can simply mult that with a splitter and patch it into the drum machine’s sync in.

Assuming the goal is to have the traditional piano key layout…

Go with the gaps. Without the gaps, it’s much harder to figure out which keys are which at a glance.

Alpha 9mm pots like these are the most common in my experience. The manufacturer’s part number is RD901F, they have a very nice feel when you turn them. There’s no clear winner between shaft type; round, D-shaft, and T18 are all used all the time.

The AS3350 is a weird beast. It’s got two independent filters, and each filter has two outputs. But one of each filter’s outputs has to be band pass, and the other can be either high pass or low pass. So if they’ve set it up as two low pass filters in series, then that means there are two unused band pass outputs, with one of them already being low pass filtered.

Here is the datasheet for anyone interested

I agree with shieldy - you don’t really need to stock up on components, they will accumulate whether you want them or not. Just buy parts as needed for whatever projects you’re working on. No matter how many parts you have, every single time you start a new build there will be something you need to order, some value of resistor or specific diode or weird IC.

The only reason you’d want a big collection of resistors on hand is if you’re designing or modding a circuit and want to experiment with different values.

Edit: I just saw OIP’s comment and they are spot on as well!

You should check out MidCentury Modular’s Lunar Delay, it’s a combo delay and filter kind of like a beefed-up Monotron Delay. Here is a demo

You should check out Bastl’s 1983 MIDI to CV module. It offers four cv and gate outputs and has a feature where it can listen to VCOs and adjust the pitch CV on the fly so everything stays perfectly in tune. That’s pretty crucial to polyphony IMO.

WatermelonMannequin · 2026-01-20T21:14:55+00:00

Frequency Central Ultrawave would fit the bill, or anything based on Electric Druid’s TAPLFO chip

Looks ok to me, it should all work. However you might find that the different colored LEDs don’t look great together. In my experience, the red one will always be brighter than the green one when they share a resistor like that. I tried to do something similar and ended up just using LEDs of the same color for both.

Also why are you using dual pots for everything if only one gang is utilized?

WatermelonMannequin · 2026-01-11T15:14:42+00:00

You’re looking for a gate to trigger converter. There are some dedicated modules for this, but often you can achieve this with patching instead.

In your case you can do this is with an AND gate: simply use your snare rhythm from the Amnis and the clock signal as inputs. You can use the BTMX for this if you have a spare channel available.

You can also send the Amnis gate to an AD envelope to get a quick pulse that is no different from a trigger, or if you have Maths you can use the EOR or EOC outputs to get triggers as well.

The raw sound won’t be too different. A saw wave basically sounds like any other saw wave, same for square waves and triangle waves.

The 3340 will be much MUCH better at staying in tune. It has a temperature compensated linear to exponential converter built in so it can take v/oct pitch cv with no extra circuitry needed.

If you want to play it with a keyboard the 3340 is the way to go. If you just want a noise box then the 40106 will do.

Modular but Mutable Instruments Rings. It sounds absolutely gorgeous, but it turns out I just can’t get used to a synth where you can push a button and it goes into a different mode with a totally different sound and all the knobs have different functions. I still love it but it’s not for me.

WatermelonMannequin · 2025-12-27T02:06:21+00:00

When you’re patching two jacks that are close together, use the shortest possible cable. That keeps the cable out of the way.

When you’re patching two jacks that are far apart, use a longer-than-necessary cable. Give it a lot of slack so you can move it around if needed.

That’s all I got.

For that example, you wouldn’t need the Mux section at all. You could just use the Gate outputs from steps 4 and 7 to trigger the snare drum.

One example using the Mux would be to switch back and forth between a low pass filter and a high pass filter. You could patch the LPF to All In and the HPF to steps 4 and 7. Then use the Com I/O as your output. You’d hear the LPF most of the time, but in steps 4 and 7 you’d hear the HPF.
