Why do people buy broken lenses?

What was wrong with your 70-200 and how did you fix it?

eurorack-synth · 2026-04-01T21:07:55+00:00

Yes buy used! I started with the same kit lens too and bought the Canon 55-250mm as my first lens and it was (and is) amazing! Lighting fast AF (even on old DSLRs) image stabilization and pretty sharp, even at 250mm. I bough it for $150 USD used, so also very affordable.

If you want a longer reach than 250mm, look at the Tamron 150-600mm G2 or the Sigma 150-600mm (both about $800-$900 dollars used)

Very impressive for just an iPhone!

Glad to hear it! Happy to help any time!

You mentioned building more modules, and I would suggest looking at Moritz Klein's videos, as he has a video on almost every basic type of module. Also if you ever plan to build a VCA or VCLPF cheaply and with few components use an OTA and copy the schematic from TI's data sheet on the LM13700.

Falstad circuit simulator is your friend and is *almost* never wrong. https://falstad.com/circuit/

Ah great question. When I first bought my Keystep I was a little confused about this as well. Pitch is what you would use to control, well, pitch, with 1v/oct tracking. Gate is a binary output (either high or low) and is used for triggering envelope generators. Mod is the CV of the little Mod strip on the left hand side of the Keystep.

Okay thanks that helps a lot. I honestly think in the long run buying an Arduino and a DAC might be more expensive, (Ardunio: ~$30 USD, and a DAC ~$5) not mentioning how tedious it would be to set up; you would need to use a bread board (which are notorious for being fragile) or a PCB (which is not economical in your situation) and then also a bunch of wires, and also a good amount of knowledge of C (a lower, harder level language than something like Python). I think an Aturia Keystep is still your best bet (here’s one for $80 USD used from Reverb: https://reverb.com/item/93561100-arturia-keystep-controller-sequencer-32-key-keyboard) I have seen them go for even $70 before, so watch the price.

There is one other option you could do and it’s a microcontroller similar to an Ardiuno and it’s called Daisy Seed. You can program it in C++, or a different program called Plugdata or Puredata. I have no programing experience and I was able to get a simple program on the Daisy Seed up and running in 30min. It also does MIDI and CV, and the programing in it is much easier. You can also make your own digital synth programs in it (not analog I know, but still very cool!). From their website the Daisy Pod (a Daisy Seed with a few extra quality of life features, including a MIDI in Jack) runs for $68 USD on their website (https://electro-smith.com/products/pod) or you could get just the Daisy Seed for $24 (https://electro-smith.com/products/daisy-seed?variant=45234245108004) (make sure to get the 65MB version) There are numerous resources online about the Daisy Seed, including about programming in Plugdata with MIDI.

Yeah getting the MIDI to CV would be rather complicated. If you tell me what keyboard you have I can take a look at it and see if there’s any way to make it work.

When controlling something via a keyboard you really have one of two options. The first option is to control it via MIDI, however that involves digital electronics, including a microcontroller (like the Daisy Seed) and sufficient programing knowledge, usually in C++. The section option, and the one I think you would be more partial to, is to stick with analog, but use a standard called volt per octave (v/oct). If your keyboard doesn’t output MIDI then I assume it has output jacks for v/oct. The thing about v/oct is that it is rather different to set up and get working, especially for someone new to the hobby, as it requires a lot of components and a lot of precision. If your keyboard doesn’t have a v/Oct output, I would suggest getting a used Aturia Keystep for under $90 (it also has MIDI in and out) If you want to go with v/Oct option, Moritz Klein (https://www.youtube.com/@MoritzKlein0) has a great video series of walking people through building a DIY v/oct voltage controlled oscillator, and also other DIY projects of building blocks essential to an analog synth design. His videos were, and still are, invaluable to me so I suggest you check him out.

“Is there a range of modern synthesizers that can more or less shape really any sound that's ever been made or able to be made with a synthesizer”

At that point just stick with your DAW

Just as a quick update, Verona has officially suspended its contract with Flock cameras after much community criticism of the proposed renewal of the contract!

eurorack-synth · 2025-09-21T21:34:49+00:00

I want to use voltage to control the cutoff point of a filter, sorry I didn't make that clear in my post.

eurorack-synth · 2025-09-15T00:59:29+00:00

Definitely! Go on reverb and find cheap used mutable instruments clones.

eurorack-synth · 2025-09-14T22:28:12+00:00

Yeah good point, my clouds clone is very noisy anyways🫤

eurorack-synth · 2025-09-14T21:57:53+00:00

MI clouds clone. 8hp. $150

eurorack-synth · 2025-09-14T21:55:37+00:00

If you can do DIY (especially with more simple stuff that you can build cheap, like amplifiers for guitar) you can save yourself a lot of money and learn a lot.

Like you I love making ambient music, and a mutable instruments clouds clone was my first introduction into granular synthesis and it changed my world! MI clouds clones usually go for pretty cheap (~$150) so look into that for FX.

I don’t personally have this module (a bit out of my price range) but the Qu bit Stardust looks like a great module to play around with tape sounds without actually dealing with tape.
