Logic: machinedrum triggering S3000XL and this audio recording

First syncing was incomplete.

Tempo in on at machinedrum.

MIDI clock: Send song position pointer on at Logic.

Machinedrum starts from bar 1.

Sync configuration solve audio head problem?


Setting for Native Instruments Traktor Scratch Pro 2 Audio Latency and Jumpiness On Nec Lavie (Dee-Jay)

Fundamental resources to do this.


First download this tool.


Set processor schedule, prior background service than program.
Computer > Property > Advanced System Setting! > Advanced tab! > Performance > check Background service

Checked diagnostics of A/I control panel.
Latency 1500ms when 96khz, 1024 buffer samples
It’s almost same when 44.1khz,512 samples.

My present situation is seldom jumpiness.

Next should try BIOS ?

No, just stop one driver was enough for me.

Used LatencyMon Drivers analysis.
My case “ACPI.sys for NT ACPI driver” was cause.

Stop this driver from Device driver > Battery > Microsoft ACPI-Compliant Control Method Battery > Right click and stop this driver

Solved my latency problem.
This is much worse than using wifi adapter.LoL.



Next time I used Traktor recording error occurred again.

Cause windows update, I don’t know.

Perhaps i8042prt is being used by Internal Keyboard and this is the cause…

I wanted to update BIOS but not supplied by NEC “NEC Lavie LL700/VG6W”.

Found newer version of Traktor



Driver version updated from 2.9.6 to 4.2.0.

Firmware is the same.

The problem still persisting…

qtractor installing a lots errros.

My case it needed

sai means “sudo apt-get install”


*checking for Qt library version >= 5.1… no; Qt 5.1 or greater is required

-> sudo apt-get install qt5-default


*configure: error: *** SNDFILE library not found.

-> sai -libsndfile-dev


checking for qmake-qt5… no
configure: error: qmake-qt5 not found in current PATH. Maybe QT development environment isn’t available. (qt5-devel)

->sudo apt-get install qt5-qmake

Next I tried below commands but don’t know was necessary.

{-> sai qtchooser

->export QT_SELECT=5}


-> sudo apt-get install qt5-default



checking for sndfile… no
configure: error: *** SNDFILE library not found.

-> sai -libsndfile-dev

And then, did
“sudo make” and “sudo make install”

->sudo apt-get install qttools5-dev-tools





Music from Youtube: Ami Suzuki “Love the island”


My new demo song reminded me this song.

The the words of this song spiked me.

Wanna listen 12 times.😤


※love the island 過ぎてゆく 小さい毎日が 気まぐれと ずっと遊んでいたら こんなに時がすぎていた

※※love the island 忘れない はじめて夜空の下で 抱き合っていたい やっとわかった あなたを思い出しすぎている

ゆっくりと静かに 気付かれず忘れたい

綺麗に焼けていく肌と 乾いてる心を 慰めてくれるのは 街並みのイルミネーション

また今度ってじらされて 涙も流したかもね 何だって教えてくれた あの夏を忘れられない

love the island 深呼吸 している 座り込んで 愛は結局出会っても 不安で何も楽になれない

本当はあなたの 目の前で思いきって 泣いてみたり笑ってみたり 怒ってみたりさせて欲しかった
穏やかな一日も あなたへの想いはつのる

海を3時間ちょっと 飛行機で飛び超えた

空港ではきかえた サンダルがちょっとてれてる

また出直しだから いくらでもどうにでもなる

旅立ちの季節かな? 少しだけ夢を見させて
※love the island 過ぎてゆく 小さい毎日が 気まぐれと ずっと遊んでいたら こんなに時がすぎていた

※※love the island 忘れない はじめて夜空の下で 抱き合っていたい やっとわかった あなたを思い出しすぎている

ゆっくりと静かに 気付かれず忘れたい mu…




Roland Space Echo RE-201 fix

My precious effecter  Space Echo RE-201’s pinch roller was crushed by mistake.
I used cleaner for tape deck’s pinch roller made of alcohol and ionic water.
And it was too much. That made its rubber harder and slippy.
Echo became dull, noisy and noncontinuous.

But silicon oil spray and sand paper treatment recovered, at least using tape leader pole.

I cleaned spring reverb also.
Touch spring directory makes awesome sound told youtube.

Maintenance of electronic musical instruments

I’m maintaining S3000XL, S900, M-160, Re-201, etc…
I opened S3000XL, S900, M-160 but not Re-201 yet.
Once I tried to open Re-201 and failed, I dropped a parts while I was removing screws and I left it to Official Support Center of Roland.

I’m using this contact cleaner

And Kure 5-56…😃

I could remove at least 50 % of contact noise with them!!!

But someday I want to wash print circuits, change some parts of  them like op-amps, power supply cables, etc …

And Re-201 needs demagnetize of heads, cleaning of roller, tape replacement etc…

Midi Thru

“What is a MIDI Thru?
A MIDI thru port provides a copy of the MIDI signal arriving at a corresponding MIDI in port. The data from the MIDI THRU socket can then go forward to the MIDI IN socket of another receiving device. … Software elements involved with routing MIDI data in computers are sometimes called MIDI thru utilities.”
Machine Drum’s Midi machine won’t output signal to Midi Thru.
That’s natural, but able to routing Midi signal from MachineDrum Midi machine to Midi Thru was preferable in my case…

Akai s3000XL – Floppy Disk Drive cable replacement.

Normal FC-40P Data Cable replaceable? — Flat cable?

I have also S900, I heard it can use Zip drive.


I’m considering connect Mo drive to Akai S3000XL by this cable.

SCSIケーブル DB25オス-HDB50オス

Akai S3000XL archive of official page

My Ubuntu could install Mesa by wine but couldn’t Launch…

This site seems funny

I remember, Once I replaced Akai S900 floppy disk drive and EL Back-light.
*Floppy drive
*Flat cable

DTM Error

What I met errors today.

1. Cables length lacks

2. Traktor 2 ratency problem on my DIY PC

3. S3000XL “cannot deleted loaded flash sample” problem
Vol problem? Certainly in the past I could delete.
=> It was item delete, from “edit sample” I could delete samples!!!

4. My PC software doesn’t receive Midi keyboard outputs.
