Have the right skills, tools and test gear to build your own modular synth, then our kits of parts may be just what you need. As a minimum, you will need to be able to identify electronic components, recognise when they need to be correctly orientated, to be able to use a small soldering iron and finally have access to test equipment. Some modules do not require the use of test equipment but any requirement will be in the 'Setting and Trimming' notes.

The kits include all required electronics components as well as pots & switches. The PCB, connectors and knobs are not included but available from Soundtronics as an option. Our, front panel + matching back panel* really finish off the module in a truly professional way. If you purchase the PCB and components through Soundtronics, then we will also support you with technical assistance just in case you get into any build difficulties.

We only source quality components and we even include the more expensive turned pin IC sockets as we feel the product justifies the extra cost both for reliability and serviceability. Our optional 1/4" jack sockets are by Switchcraft, yes you can save money by buying cheaper sockets hence us offering it as an option because we recognise they are a significant cost. We have standardised on Cliff KM20 knobs for all of our modules but again, as it's an option you can choose different knobs to suit your own preference. Finally, all components are available individually should you not need to purchase the whole kit.

Note

On test, we experienced problems in getting the core ramp generator to oscillate. The YuSynth designer has two voltage regulators feeding the core part of the circuit +Vcc & -Vcc. These are intended to provide a degree of voltage stability to the core circuit and should give around +/-14.2V if using +/-15V regulators on a +/-15V supply. We actually found +13.63 and -14.7V. There are two precision resistors R49 and R50 used to create a 5V reference whioch can only happen if Vcc is 15V, not 13.63V as in our case. We decided to remove the two voltage regulators and bypass them on the basis that the synth power supply we use is very stable and any small fluctuation has an insignificant effect in comparison to the drift due to temperature changes. YuSynth has warned that bypassing the on-board regulators could require a number of resistor values to be changed. We found the circuit performance was not affected and the original resistor values were kept. Your choice as to whether to follow the same route as we did or stick to what is a proven design and looks to work in most cases.
