Portland Board Street Art



Here is a collection of photos of a new type of street art which started appearing in Portland, Maine a few years ago.

Each piece consists of a painted board attached to a street sign with wire. The earliest photo dates to 2017.

Kurzweil K2000 OS ROM Upgrade



This tutorial will show the process for upgrading the OS for the Kurzweil K2000 synthesizer. The OS itself is stored on two EPROM chips, called the Hi ROM and the Lo ROM. This upgrade was purchased from SynthPlus on eBay, as the original upgrade is difficult to get directly from Kurzweil. I've followed their guide, which is available here. Some steps were slightly different due to the PRAM upgrade in this unit.

MSYN_SK Sample Pack



Here is a new sample pack produced using a Seaweed Factory MSYN Microsynth. The MSYN is a tiny microsynth containing an oscillator which modulates another oscillator, followed by a gating circuit with variable gate width. The entire signal path is analog and built around a 40106 hex inverter IC. Each sample was then processed using a modified Casio SK-1 Sampling Keyboard to give the synth tones more weirdness and distortion.

A similar sample pack was produced for the TX81z and SK-1 some time ago.

Akai MPC 1000 Reverb Impulse Response Pack



This is a collection of impulse responses for the reverb effect on the Akai MPC 1000 sampler. These files can be loaded into a convolution reverb to simulate the processing of the Akai MPC 1000. Each response was recorded directly using a transient sample. The reverb effect has four parameters:

Input Filter
Time
HF Damp (High-frequency damping)
Reverb Level


Input Filter was set to 32 for all samples to fully open the filter and bypass most of its effect. This could be simulated by adding a filter plugin before the convolution reverb. Reverb Level was set to 99 to get the maximum possible signal level. Time and HF Damp were varied for each sample to allow a range of options. Time was sampled in roughly 10 unit increments, from 0 to 99. HF Damp was sampled in 8 unit increments, from 0 to 32.

The filenames are marked with the settings. For example,

MPC1000-HF24-T30.wav

means HF Damp was set to 24 and Time was set to 30.

Yamaha EMP100 Impulse Responses



Today we have a collection of impulse responses for the Yamaha EMP100. These files can be loaded into a convolution reverb to simulate the processing of the Yamaha EMP100. Each response was recorded directly using a transient sample. Only reverb and early reflection (ER) presets were sampled. Each file is labeled with its original preset number and title.

Here are descriptions from the patch list provided with the unit.

01 Large Hall Reverb 1
02 Large Hall Reverb 2
These two programs simulate the reverberation of two different large halls. Both are excellent "general-use" reverb effects.

03 Room Reverb 1
04 Room Reverb 2
These effects produce the type of reverberation you'd experience in a small to medium-size room with hard wall surfaces. Both are particularly effective with drum or percussive sounds.

05 Vocal Reverb 1
06 Vocal Reverb 2
An ideal reverb effect for use with solo vocals or chorus.

07 Plate Reverb 1
08 Plate Reverb 2
These are relatively "soft" reverb effects that are well suited for use with strings or brass.

09 Hall ER
This is a straightforward early-reflection effect that has a distinct "gated" feel.

10 Random ER
A somewhat "rougher" sound than the Hall ER program.

11 Reverse ER
The level of the reflections increases rather than decreasing with time, producing an effect similar to that of a tape recording played backwards.

12 Spring ER
This program simulates the sound of a spring reverb unit, and produces a much tighter sound than the Hall ER program.

31 Piano Hall
A natural reverb simulation that is ideally suited to piano.

34 Church
This is a reverb program that will make organ voices sound as if they are being played in a spacious church.

38 Attack Brass Reverb
This sharp, short reverb effect will help brass section phrases to stand out.

64 Room Ambience
An excellent effect to add ambience to rhythm machine sequences.

65 Hall Ambience
A very reflective, "live" ambience for all types of drums.

66 Bright Ambience
A basic but bright ambience that can bring your drum sound to life.

67 Tight Ambience
This tight, punchy reverb is a good choice for simple drum phrases.

68 Hard Room
This is a rather pronounced ambience effect that can be used for a range of instruments in addition to drums.

69 Kick Reverb
Recommended for use with rhythm machine bass drum sounds. Also good for toms.

71 Snare Reverb
An orthodox snare drum reverb effect.

74 Reverse Gate
A popular effect for a wide range of drums and percussion sounds.

75 Percussion Gate
Indispensable for cowbell, conga, and other percussion instruments that have a strong attack. Can really being an instrument forward in an ensemble.

76 Percussion Reverse Gate
A reverse gate created specifically for use with percussion instruments. Use on instruments you want to stand out.

79 Percussion Reverb
The fundamental reverb for all percussion instruments. You can lengthen the reverb time a bit to make this effect perfect for use in slow tunes.

80 Percussion Room
A very spacious reverb that is useful with all percussion instruments.

81 Percussion ER
A fairly short gate-like effect adds a unique touch to percussion.

82 Shaker Reverse
This one adds a reverse effect to shaker sounds. Try it for extra impact in introductions.

85 Vocal Reverb
A basic and very useful reverb for vocals.

88 Bathroom
This effect should need no explanation. If you've ever sung in the bathroom, you've heard it before.

98 Long Tunnel
Quite a reverb - about 12 seconds worth, in fact.

Roland D-10 Battery Replacement



This Roland D-10 was sitting in a local vintage shop going unused because all its patches seemed to be stuck in split mode. A quick check online produced this forum thread. The synth was purchased with hopes that a new backup battery would correct the memory problems.

Here are the steps that were used to replace the decades-old backup battery.
