128 notes and 4 DSPs. (!!!)
It sounds like a PSR 1500 of 2004 (sold for the equivalent of ~1 k€ current day money), not a top of the line arranger of 2023 (probably retailing at 4÷5 k€).
HW arrangers have always been old tech, lagging 15÷20 years behind other more mainstream computing devices. The PSR 1500 in 2004 was no exception.
Here we are adding another 20 years of lag on top of the usual and standard 20 years. Totaling a whopping 30÷40 years ”late to the party” retro computing technology.
And, by the way, the PSR 1500 could play flawlessly not less than 20+ different chord shapes in all the 12 keys.
I need to respond to such posts just because there are others who read this and if they do not see a response, take it for its value.
More Polyphony is needed more for purely MIDI-based arrangers and less for Hybrids (Midi + Audio). So when you quote a Midi based arranger having 128 notes some years ago, you are correct, but comparing that or equating that to an Arranger with both Midi and Audio can't be true, let alone an instrument that is streaming 5 Audio tracks together at once! The KETRON AUDYA is a Hybrid (Midi and Audio) Arranger with 196 notes of Polyphony.
To give others a perspective so they are not lost - when you play your Wav/Mp3 song, your 'player' sees it as 2 tracks (Stereo), so you get all these sounds coming off 2 tracks; therefore in the Midi world, your player is 2 notes polyphony as it can play a max of 2 'tracks' at a given time. So if you have a keyboard that can play 6 audio tracks that has 128 notes assigned to Midi playback, that is a HUGE leap forward in today's technology, especially when it can play that AS AN ARRANGER in conjunction with any style (chord changes in real-time, tempo changes in real-time), a feature no PSR to date can do effortlessly, and so while the technology in many Midi Based Arranger may be outdated, those in the Hybrid Arrangers are just beginning to show their "strengths" and yes, weaknesses too.
I hope this clarifies this for others out there who are reading this post.
