That's odd. I believe the samples are stored in ROM, so not much you can do...

Is this with the standard drum bank, or with an alternate bank?

To Hunterz: Not sure what you mean by standard or alternate bank.
To Mau1: I know it's weird. 4meg rom and only drum sound is missing. I got this off Ebay. There is no obvious physical damage that I can see.

First noticed with streets_of_philadelphia.mid bcause it has very noticeble continuous drum track. Roland scd is not playing the drums at all while my other two boards have no problems.

rolandfan: GM/GS/XG synths have alternate "banks" of sounds that can be selected. For drums specifically, GM has several selections including Standard 1, Standard 2, Room, Jazz, Power, Orchestra, Brush, TR-808, etc. I was just wondering if maybe some of the MIDI music you're playing uses a drum bank that isn't fully supported by the SCD-15.

Rolandfan you could post the midi file here and I can play it on a SC-55 and see what it sounds like or even record it...

To Mau: Ok I think it's best that I post the midi file.
To Hunterz: Ahh I didn't know that. That explains why sometimes I hear drums. It must be then the GM drum section is missing/damage/corrupted

anyway here it is.

Coolies!

Well I can hear drums just fine. On my Roland SC-55 display they play on channel 10 if that helps.

Here is a MP3 recording: http://www.mediafire.com/?499nauc7qyhlm0n

Good midi by the way...

On mine drum sounds are completely missing. Now I gotta track down roland utility.

Edit: ok digging up floppies. found Doremix. according to roland info site individual patch can be turned off or on. Maybe doremix could try to turn it on?

I think others here may have an SCD-15. Would be interesting to see if they have the same issue. Could it possibly be an issue with the host sound card?

🤣, never thought I'd get so attached to a piece of 16 yr old pc hardware.

To HunterZ: I'm not quite sure if it's the host card because I have two other daughterboards(not roland) and they play everything fine zero problems except occasional hanging note here and there. But I like roland.

Yeah I've used search and found no answers so I started this thread.

I've included the recording to demonstrate the problem.

It does look like your SCD-15 is a bit sick 😢

If the other 2 cards works just fine I can't think of anything else "blocking" midi channel 10 just on your SCD-15...

It might be time to look for a new card. I always recommend getting a external Sound Canvas (SC-55, SC-55MK2 or SC55ST)

I can personally vouch for the SC-88 as well, which has an SC-55MkII mode.

+1 🤣 There are a ton of Roland modules that are compatible!

A good overview can be found on wikipedia: http://en.wikipedia.org/wiki/Roland_Sound_Canvas

Ok thanks,

Next year I'm going to label my retro boxes, so I know what's in them and where to find things! 😉

I have a SCD-15. I don't use it on SB16 anymore because it always has had wrong note / stuck note problems with them.

I've found that it works fine on ESS cards and Vortex cards, although the Vortex MPU401 doesn't always work with some DOS games. However, the Vortex cards have much better analog circuitry and the DB sounds great on them. I haven't tried other DB headers. I wish I had a MPU401 card but they are very rare.
