psr voice generators

[anon125]

Does anyone know which voice generators are used past and present?

I asked Yamaha if the voice generators for the old  psr e313 are the same as current ones and would they sound the  same?
their reply in part was "The voices sources are different on PSRE363 and PSRE463/410. They do not sound identical"

can anyone answer my question?
thanks all

The Service Manual for the PSR-E443 says it uses the SWL01U chip.

The Service Manual for the PSR-E313 says it uses the SWL01 chip.

I can't find a Service Manual for the newer models, and I don't know what the differences are between those chips. Maybe PJ can help with that?

I also don't know if they meant that the chips are different, or that the sound samples are different.

Do YOU notice any difference in the sounds of each keyboard?
PSR-EW400 is the one before the 410.  Does the piano and other voices sound better?
altho both keyboards seem to have the same speaker size the psr e313 sounds downright tinny compared to our psr 4600.

Yamaha stepped up their game with the PSR-E453 and successors. AWM2 tone generations is pretty much the same in all models. The number of tone generation channels, waveforms (samples) and digital effects vary depending upon generation.

Prior to that model, SWL01 (and variants) were widely used. The CPU and tone generators are integrated in one part, the SWL01. The SWL01 has 32 tone generation channels and minimal chorus/reverb effects.

Yamaha introduced the SWX03 starting with the PSR-E453. The SWX03 has 48 tone generation channels (i.e., polyphony) and ten DSP effects in addition to chorus/reverb.

I believe that Yamaha also made improvements in the waveforms beginning with the E453. Even the PSR-E363 claims "improved sampling." The E-series waveforms are still not up to the same level as the S-series.

Hope this helps. I can gab about this all day, but it might be a case of TMI for folks who just want to make a purchasing decision.

All the best -- pj

how do i tell this forum to email me when some kind person replies to a post? most forums it is just below the text area or in the profile.

I wonder why our psr 4600 probably from around 1990! sounds far better than the psre313!
we are looking at maybe the 363 463 410. do they sound fine in a normal room?
our 313 needs headphones to get better sound. so the good enough sound is in there but the amp and speakers are clearly limited.

thanks
