Beautiful music! Great video. Congratulations to your new Korg Trident. I’ll get mine next week.

just beautiful....

Sounds excellent with the reverb on it.

Imho, the sound of the Trident is so richt that a little bit of reverb is enough to make it sound spectacular. It comes with a fantastic BBD based flanger that you can assign to a section (synth, brass or strings) of your choice, and the string section has a BBD based 'ensemble' effect. The sound is so big that it is hard to believe that it is mono. For a super huge string sound, I like to make two recordings and use them as left and right channels.

@@GNeuman Thanks! I'd love to use it on a few tracks (and I certainly will) but I guess I'd better be patient and wait until I have replaced the power supply with something more reliable. I have heard horrors stories of Polysix power supplies failing and destroying the whole synth, or of Juno-60 power supplies heating up to 70°C... I did recap it and reflowed the solder around the regulator legs, and when one of the old plastic screws that were used to attach the regulators broke and sent the regulator into thermal shutdown, I attached it again it with a proper screw and nut, put new silicone pads between the regulators and the (tiny!) heatsinks and new heat paste between the heatsinks and the housing. It works but it gets too hot for my taste, and I don't trust the old regulators. The plan is to design a "state of the art" external power supply.

@@GNeuman The plan is to start with the original schematic, make everything a little bit bigger (especially the regulators and the heatsink) and better, put it into a rack case and maybe add a few meters on the panel www.amazon.de/dp/B07GPFP1JB/ref=sspa_dk_detail_2?psc=1&pd_rd_i=B07GPFP1JB&pd_rd_w=IdNpS&pf_rd_p=80f139ed-36cd-4376-aa65-33f3cf0faca3&pd_rd_wg=BMMKl&pf_rd_r=YFM2AJ6TGJY8SWFBMFWH&pd_rd_r=1d68b3a2-bd95-45f0-9718-dbe4c8d3d9cc&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFMN0U1RE1SVlU2MlkmZW5jcnlwdGVkSWQ9QTA4ODgyMzYxUFgwSzA4Q0tIUDFTJmVuY3J5cHRlZEFkSWQ9QTA3NjMxMDgzNUhSMzc5RFM2TVpHJndpZGdldE5hbWU9c3BfZGV0YWlsJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== and safety features that shut the whole psu down if voltages or currents are unusual.

That is what the Trident was built for ..fabulous. Did the sound change after Re Cap ? Mine get's warm.. My Power Supply been recapped too.

I had to recap the whole instrument because many caps were leaking and corroding, especially the 10µF, 47µF and 100µF ones. Fortunately, I discovered it just in time so that the PCBs are still fine. Before recapping, there were all kinds of noises and crackling going on, which was quite frightening. After recapping, all the noises were gone. I noticed a dramatic change when I replaced the 47µF caps in the synth vcf section with organic polymer capacitors (recommended by my brother who is currently doing a PhD in Electronic Engineering): Suddenly, the sound was much clearer and more transparent without losing its warmth and body, and there was a lot more going on in the very high frequencies, which worked very well with the cutoff and resonance. However, since organic polymer capacitors have a relatively high leakage current and since I have not yet had time to fully understand the potential unintended consequences this might have for other parts of the synth (such as the psu), I removed them and put good old 47µF electrolyte capacitors in again. If your sound gets warm in the sense that there is less going on in the high frequencies (>10kHz), this could very well be caused by the transmission characteristics of your new capacitors. As for the Power Supply, I must admit that I don't trust it. I have recapped it but had a problem with a regulator. It also gets very hot and thus cooks the inside of the synth. This is quite common with many older synths such as the Polysix (famous for its unreliable power supply) or the Juno-60. I am considering to design a more powerful external rack mount power supply that is has all the necessary safety features.

P.S.: I am currently restoring an old 12 channel mixer and use organic polymer capacitors as replacements for the old caps. They sound great - clear and transparent! Here is a brief summary: "Aluminum organic polymer capacitors make major improvements over traditional liquid-electrolyte-based aluminum electrolytic capacitors. This paper describes the advantages and disadvantages of traditional electrolytic capacitors, and explains how organic polymer capacitors offer improved performance." www.digikey.com/en/maker/blogs/aluminum-organic-polymer-capacitors "Organic polymer capacitors have up to five times less ESR than similarly sized electrolytic capacitors. Reduced ESR means fewer capacitors are required to do the same job-they run more efficiently and improve the frequency response of the capacitor. ESR is also more stable over temperature than aluminum capacitors, whose ESR increases dramatically at cold temperature. ESR is also more stable over frequency."
