Quote from: Stefan_L on April 26, 2010, 03:14:48 AMI just built it and it works fine with my MU10 I will post some more details how it is connected later.Is there any way of lowering the output signal of SPDIF? it is so loud wich makes many songs clip
Quote from: Stefan_L on April 30, 2010, 04:58:33 AMPin 23 of the DIT is connected to VCC... but i tried to connect it to ground also just to test but there was no difference.The sound is clipping from the DAC (AK4510) in the MU10, so i guess it's the natural sound of MU10 Actually this was the main reason i wanted to spdif mod my MU10... i wanted to get rid of the clipping sounds as i thought it could not happen if the signal was digital.
QuoteAnd about your 230mb soundfont... here is the two midis:http://www.ym2149.com/mu10_spdif/JAMMA.MIDhttp://www.ym2149.com/mu10_spdif/Paths.midSBlive has not a chance against the mighty 4mb of the MU10
Quote from: butter_pat_head on April 30, 2010, 08:50:41 AMAre the two MP3 recordings meant to have examples of the clipping? Because when I listened to them they sounded OK to me through my AV receiver and Hi-Fi speakers.
Quote from: Stefan_L on May 14, 2010, 03:39:38 AMA thing i might point out is that when i connected the wires to the dit4096 so did i solder directly on the DAC pins and not thfrom the holes i marked in the pic in the first post (with exception of masterclock). the clock pins goes directly to the DAC but the data goes to the chip that is to the top right corner seen in the bigger MU10 pic i posted (marked XR976A0).If i connect the dataline before it goes thru that chip then i get a louder volume signal wich crackles alot and seems sensitive to higher sounds? here is an recording (excerpt from Random Paths)http://www.ym2149.com/mu10_spdif/randompaths_data_fromxgchip_notdac.mp3I did get a better sound when get the data after it passes thru the XR976 chip as you can hear, this would mean i can't modify the DB50XG as it does not have an XR976 chip.I am speculating if this has something to do with the fact that the DB50XG has 18bit DAC(nec D63200) while the MU10 has a 16bit DAC(AK4510)... i mean the data needs to be converted from 18bit to 16bit on MU10 before it goes to the DAC?
Quote from: bitbull on December 23, 2020, 05:24:14 AMthe Yamaha MU100, which has a D63200 DAC too.Which pins of the D63200 (WDCK, CLK, RSI, SI/LSI) did you connect to which pins of the DIT4096 (MCLK, SCLK, SYNC, SDATA)?
